Correctly multiply (3x + 7) (7x + 5)
Then find the sum of the coefficients of your solution.

Answers

Answer 1

Answer:

The sum of the coefficients is 85.

Step-by-step explanation:

(3x + 7)(7x + 5)
3x * 7x is 21x^2
3x*5 is 15x

7 * 7x is 49x

7 * 5 is 35

21x^2 + 15x + 49x + 35

So the answer is 21x^2 + 64x + 35

Add the coefficients: 21 + 64 = 85

The location of Sam's house, the library, and the gas station are shown on the map below.
Based on the map, what is the shortest distance, to the nearest tenth, from the Library to the Gas Station if each unit represents one mile?

Answers

It is found that location of Sam's house is at a distance of approximately 8.062 meters far from the gas station.

What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]  

Sam's house S(x, y) = (2, -4)

Library L(x, y) = (-5 , 2)

Gas station  G(x, y) = (3, 4)

The distance d, in miles, is determined by the line segment distance formula:

D = √[(x-p)² + (y-q)²]  

It is used in an operation known as dot product.

Then the distance between Sam's house and the Gas station is:

D = √[(2 - 3)² + (-4 -4)²]  

D = 8.062 meters

Hence, The location of Sam's house, is at a distance of approximately 8.062 meters far from the gas station.

how do you solve graphs and make an equation from a line on a graph?​

Answers

Ans: To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept (y=mx+b) form. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points.

Always start on the y-axis.

rise/run

First things first, you have to know your positives, negatives, zeros, and undefined.

To make an equation from the graph you have to know your formula.

y=mx+b

You do the rise first. The rise on the graph is 3. The run is 2. So, that'll make it 3/2. m=slope.

b=y-axis. b=1.

Step-by-step explanation:

The angle A inside the triangle is

180-162 = 18 degrees

The measure of angle N inside the triangle is

180 -  149 = 31 degrees

Now, since we have the inside angles we can find ang P

Inside Ang A + Inside Ang N + Ang P = 180

18 + 31 + P = 180

49 + P = 180

P = 180 - 49

P = 131 degrees

Which number is not an appropriate result?
A - a shopping receipt that totals $4.90

B - a soccer game where the average score is 4.7

C- a stack of 15.6 watermelons

D- a classroom with 24 students

Answers

Answer:

C - a stack of 15.6 watermelons

Step-by-step explanation:

Lets first go through each option:

"A shopping receipt that totals $4.90":

This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.

"A soccer game where the average score is 4.7":

This is also an appropriate result since it is the average score of a soccer game, so finding a decimal is appropriate.

"A stack of 15.6 watermelons":

This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.

"A classroom with 24 students":

This is an appropriate result since the number of students is a whole number not a decimal.

Answer:

x = 6[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 18²

x² + 144 = 324 ( subtract 144 from both sides )

x² = 180 ( take the square root of both sides )

x = [tex]\sqrt{180}[/tex]

  = [tex]\sqrt{36(5)}[/tex]

   = [tex]\sqrt{36}[/tex] × [tex]\sqrt{5}[/tex]

A fruit stall sells three kinds of fruits - apples, oranges and pears. At the end of the day, they amount of money earned from selling apples and oranges is $372, while the amount of money earned from selling apples and pears is $480. The ratio of the money earned from oranges and pears is 1 : 4. How much money did the fruit stall earn from the apples?

Answers

The fruit stall earns 96 dollars from the apples.

How to find how much money the fruit stall earn from the apples?

The fruit stall sells three kinds of fruits which are apples, oranges and pears.

Therefore,

The amount of money earned from selling apples and oranges is $372.

The amount of money earned from selling apples and pears is $480.

The ratio of the money earned from oranges and pears is 1 : 4

Therefore,

let

x = amount earned on apples

y = amount earned on oranges

z = amount earned on pears

Therefore,

x + y = 372

x + z = 480

The ratio of  the money earned from oranges and pears is 1 : 4. Hence,

x : z

x : 4x

where

z = 4x

Therefore,

x + 4x = 480

5x = 480

x = 480 / 5

x = 96 dollars

Therefore,  the fruit stall earns 96 dollars from the apples.

Step-by-step explanation:

I'm not 100% correct, but you set the other two angles to add to each other then set it equal to angle QRS and i got x=6.

Your equation should be like this: 3x + 17 + 2x +21 = 10x -1

than you solve form there

I;m not sure that this is the correct answer and maybe i'm wrong, but hope this helps

Answer:

59°

Step-by-step explanation:

According to the given description, [tex] \angle QRS[/tex] is the exterior angle of [tex] \triangle PQR[/tex]

So, by exterior angle property of a triangle, we have:

[tex] m\angle QRS=m\angle RPQ+m\angle PQR\\\\

(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\

(10x - 1)\degree = (3x +17+2x +12)\degree\\\\

(10x - 1)\degree = (5x +29)\degree\\\\

(10x - 1)= (5x +29)\\\\

10x - 5x = 29 + 1\\\\

5x = 30\\\\

x = \frac{30}{5}\\\\

x = 6\\\\

\because m\angle QRS = (10x - 1)\degree \\\\

\therefore m\angle QRS = (10\times 6- 1)\degree \\\\

\therefore m\angle QRS = (60- 1)\degree \\\\

\huge\orange{\boxed{\therefore m\angle QRS = 59\degree }}\\

You can’t add both terms because the coefficients are multiplying different variables. It’s like trying to add apples and oranges together. They are two different things. So is this situation, variables b and m are two different things. Therefore you can’t add them together. This means that you can’t simplify the expression any further.

Answers

Sin 10° Sin 50° sin 70° = 1/8
Now we multiply upper & bottom both side 2/2

then

➡ 1/2 (2sin 10° sin50° 70°)

➡ 1/2 sin10°( 2sin70° sin50°)

we know that
2 sinA sinB = cos (A-B) - cos (A+B)

Then

➡ 1/2 sin 10° ( cos 20° - cos 120°)

➡ 1/2 sin 10° ( cos 20° - cos (90°+30°))

➡ 1/2 sin 10° ( cos 20° +1/2)

➡ 1/2 sin 10° cos 20° +1/4 sin 10°

again we multiply both upper & bottom side 2/2 so

➡ 1/4 ( 2 sin 10° cos 20°). + 1/4 sin 10°

we know that
2 sinA cos B = sin (A+B) - sin (A- B)

➡ 1/4 (sin 30° - sin 10°) + 1/4 sin 10°

➡ 1/4 sin 30° - 1/4 sin 10° + 1/4 sin 10°

we know sin 30° = 1/2

The owner of a used car lot wants to buy many cars at an auction as he can while not spending more than $20000. If he expects the average price to be $4000, how many would he expect to be able to buy?

Answers

Answer:

5

Step-by-step explanation:

Given that:

Total maximum amount that the owner wishes to spend = $20000

Average price of each car = $4000

To find:

How many cars that the owner can expect to buy?

Solution:

Total number of cars that the owner can expect to buy can be found by dividing the total money available with the owner with the average price of each car.

i.e.

[tex]\text{Number of cars expected to be bought} = \dfrac{\text{Total money available with the owner}}{\text{Average Price of car}}[/tex]

We have the following values as given in the question statement:

Total money available = $20000

Average price of car = $4000

Therefore, the answer is:

[tex]\text{Number of cars expected to be bought} = \dfrac{20000}{4000} = \bold{5}[/tex]

The owner can expect to buy 5 number of cars.

-1 5/6

Step-by-step explanation:

-2/3 + (-1 1/6)

Look carefully at he number line. Each space between whole numbers is divided into 6. That means that from one mark on the line to the very next one, the distance is 1/6.

Start at -2/3. Since we are dealing with 1/6's, convert -2/3 to 6ths.

-2/3 * 2/2 = -4/6

-2/3 is the same as -4/6, so start at -4/6. Locate 0 on the number line, and move 4 marks to the left. That is -4/6 which is the same as -2/3 and is your starting point.

Now you need to add -1 1/6. Adding a negative number is the same as subtracting a positive number. Adding -1 1/6 is the same as subtracting 1 1/6. That means you need to go left 1 1/6. Since each unit is divided into 6 equal parts, 1 1/6 is 7 marks on the number line. Starting at -4/6, count 7 marks to the left. Where you end up is the answer which is -1 5/6.

Answer: -2/3 + (-1 1/6) = -1 5/6
