Answer:
6x3+10x2−16x or A
Step-by-step explanation:
I used an algebra calculator because im too lazy to work it out.
^algebra^
(3x2 + 8x)(2x − 2)
=3x²(2x-2)
=6x³ - 6x²
+8x(2x - 2)
=16x² - 16x
put it all together
=6x³ - 6x² + 16x² - 16x
group according to variables, then count
6x³ + (-6x² + 16x²) - 16x
=6x³ + (+10x²) - 16x
=6x³ + 10x² - 16x

three consecutive odd integers are such that the square of the third integer is 65 less than the sum of the squares of the first two. one solution is -7, -5, and -3. find three other consecutive odd integers that also satisfy the given conditions
We need to know about quadratic equation to solve this problem. The other three consecutive odd integers that satisfy the conditions are 11, 13 and 15.
We need to consider three consecutive odd integers, odd integers are integers that are not divisible by 2. Odd and even integers occur alternately so the the difference between two consecutive odd integers is always 2. We will consider one odd integer x, the next odd iinteger will be x+2 and the third odd integer will be x+4. Therefore we have our three consecutive odd integers, x, x+2 and x+4. It is said that the square of the third integer is 65 less than the sum of the squares of the first two. We can write this relation as
[tex](x+4)^{2} +65=x^{2} +(x+2)^{2}[/tex]
We can solve this equation to get a quadratic equation, and then solve it for x
[tex]x^{2} +8x+16+65=x^{2} +x^{2} +4x+4\\x^{2} +4x-8x+4-16-65=0\\x^{2} -4x-77=0[/tex]
We will solve the above quadratic equation for x
[tex]x^{2} -4x-77=0\\x^{2} +7x-11x-77=0\\x(x+7)-11(x+7)=0\\(x+7)(x-11)=0\\[/tex]
Therefore we get two values for x -7 and 11, from the question we already know about -7, we will find the three odd integers from 11 now
So the other three consecutive odd integers that satisfy the given conditions are 11,13 and 15.

What is the solution of the following system of equations 5x+7y=3, 2x=-3y+1
Answer:
point form: (2,-1)
equation form: x=2,y=-1
Step-by-step explanation:
Answer:
X = 2 and y = -1
Step-by-step explanation:
add 3y to both sides of 2x = -3y + 1
2x + 3y = 1
5x + 7y = 3
multiply (2x + 3y = 1) by -5 and (5x + 7y =3) by 2
-10x - 15y = -5
10x + 14y = 6
-y = 1
y = -1
plug in y

Five positive whole numbers add up to 47
One of the numbers is a multiple of 9
The other four numbers are equal.
Work out the result when the five numbers are multiplied.
Greetings from Brasil...
According to the statement
A + B + C + D + E = 47
making B the multiple of 9
A + 9B + C + D + E = 47
as the other 4 numbers are the same, let's call it A
A + 9B + A + A + A = 47
4A + 9B = 47 assigning values to B, we have
B = 1 ⇒ A ∉ ℤ
B = 2 ⇒ A ∉ ℤ
B = 3 ⇒ A = 5
B = 4 ⇒ A ∉ ℤ
B = 5 ⇒ A ∉ ℤ
B = 6 → from now on, A will be negative
Then
A = 5 and B = 3
Multiplying all numbers:
A·9B·A·A·A = 9A⁴B = 9·5⁴·3 = 16875

Answer:
30 feet
Step-by-step explanation:
To find the distance use a trigonometric ratio. Since we are looking for the hypotenuse and we are given the opposite side we will be using the ration of sine. We can set up the equation like this by using x as the measure we are looking for.
Sin of x=Opposite leg/Hypotnuse
Sin of 30= 15/x
Multiply by x and then divide by Sin of 30 to isolate the x.
x=15/Sin of 30
Plug it in to a calculator.
x=30

A car journey has two stages.
Stage 1: The car travels 110 miles in two hours
Stage 2: The car travels 44 miles at the same average speed as stage 1
Work out the time for stage 2
Give your answer in minutes.
Answer:
48 minutes
Step-by-step explanation:
2h = 110 miles
1h = 110 ÷ 2
= 55 miles
Therefore, the speed of the entire journey is 55 miles per hour.
1h = 60 minutes
55 miles = 1h
55 miles = 60 minutes
44 miles = [tex]\frac{44}{55}[/tex] × 60 minutes
= 48 minutes
if vectors A&B are non zero vectors ,is it possible for their dot product and cross product to be zero? explain.
Answer:
It can be proved that it’s impossible.
The dot product is defined as:
a⋅b=∥a∥∥b∥cos(θ)
where θ is the angle between a and b .
The cross product is defined as:
a×b=∥a∥∥b∥sin(θ)n^
and the magnitude of this is given by:
∥a×b∥=∥a∥∥b∥sin(θ)
We also know that:
cos2(θ)+sin2(θ)=1
We can substitute the dot product and the magnitude of the cross product in here, to find:
(a⋅b)2+∥a×b∥2=∥a∥2∥b∥2
We’ve specified that a and b are non-zero vectors, so the right hand side cannot be zero. As a result, at least one of (a⋅b)2 or ∥a×b∥2 must be non-zero.

How do I solve this step for step? This is confusing..
0.125 < π < 9/50 (fraction)
The solution to the inequality expression given as 0.125 < π < 9/50 is false
What are inequality expressions?Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal
How to determine the solution to the inequality expression?The inequality expression is given as
0.125 < π < 9/50
Express 0.125 as a fraction
So, we have the following inequality expression
1/8 < π < 9/50
As a general rule, we have
π = 22/7
So, the inequality expression becomes
1/8 < 22/7 < 9/50
Evaluate the quotients
So, the inequality expression becomes
0.125 < 3.14 < 0.18
The number 3.14 is not between 0.125 and 0.18
This means that the inequality expression 0.125 < 3.14 < 0.18 is false
Hence, the solution to the inequality is false

Always remember the order of operations: PEMDAS.
7 - (3 + 5) + (-3 + 6)/3 x 5
7 - (8) + (3)/3 x 5 (solve the parantheses first)
7 - 8 + 1 x 5 (3/3 comes first since multiplication and division have the same order; you would go left to right)

What is the equation of the line that passes through the point (4, -4) and has a
slope of –3/4?
Answer:
y=-3/4x-1
Step-by-step explanation:
y=mx+b; y is the y coordinate; m is the slope; x is the x coordinate; you have to find b. So you replace all the numbers out which is given to you;
-4=-3/4(4)+b (you multiply -3/4 by 4 and get -3)
-4=-3+b (you add 3 to both sides and get -1)
-1=b (you now found b so plug it into the equation)
y=-3/4x-1

Identify the underlined place in 131.572. Then round the number to that place
The 5 is underlined
Can someone please help??
Answer:
The 5 is in the tenths place.
Step-by-step explanation:
:)
Answer:
131.6
Step-by-step explanation:
Since the 5 in 131.572 is underlined, we need to round the number to the nearest tenth. When rounding numbers, we need to look at the digit next to the rounded digit. The digit after 5 is 7.
If the digit after that is 1-4, we round down the 5. If the digit after that is 5-9, we round up the 5. Since 7 is between 5 and 9, we round the digit 5 to 6.
Thus, the rounded number would be: 131.6

Lisa spends part of her year as a member of the gym. She then finds a better deal at another gym, so she cancels her membership with the first gym and spends the rest of the year with the second gym. (12 months total at these gyms.) The membership to the first gym costs $75 per month, while the membership for the second gym cost $50 per month. She ends up spending a total of $775 over the course of the year.
Answer:
Number of month in first gym = 7
Number of month in second gym = 5
Step-by-step explanation:
Given:
First gym member ship cost = $75 per month
Second gym member ship cost = $50 per month
Total spending = $775
Computation:
Number of month in first gym = a
Number of month in second gym = b
So
a + b = 12....eq1
75a + 50b = 775 ....eq2
From eq 1 and 2
a = 7 month
b = 5 month
Number of month in first gym = 7
Number of month in second gym = 5
