Answer:
(6x - 7) (6x - 7)
Step-by-step explanation:
A perfect square trinomial will be in the form of [tex]a^2[/tex] ± [tex]2ab + b^2.[/tex] A trick to factoring a perfect square trinomial would to write it as [tex](a^2[/tex]±[tex]b^2)[/tex]. (When doing this, the sign in the middle is determined by the middle sign in the original trinomial).
[tex]36x^2 -84x + 49[/tex] is known as a perfect square trinomial, too. Its first and last terms are both perfect squares (6x squared makes [tex]36x^2[/tex], 7 squared makes 49) and the middle term is 2 times the square roots of both of the other terms ( [tex](2) (7) (6x)[/tex] is [tex]84x[/tex]).
So, we can use the trick described earlier, and the answer would be [tex](6x-7)^2[/tex], also known as (6x-7) (6x-7).

Answers
Answer: The shape below is formed from a rectangle measuring 18 cm by 24cm from which a rectangle of length 8.6cm has been removed
Step-by-step explanation:
initial Perimeter of rectangle = 2 (24 + 18) = 84 cm
After removing rectangle of length 8.6 cm
two sides of 8.6 cm are added in perimeter
Perimeter of Shape
= 2 (24 + 18) + 8.6 + 8.6
= 84 + 17.2
= 101.2 cm
perimeter of the shape = 101.2 cm

Jerry was given some birthday money. He puts the money in an account. Every month after that, he deposits the same amount of money.
The equation that models this situation is y = 50x + 75, where y is the amount of money in the account and x is the number of deposits.
What does the y-intercept mean in this situation?
A. He was given $50 for his birthday.
B. He puts $75 in the account each month.
C. He puts $50 in the account each month.
D. He was given $75 for his birthday.
Answers
The y -intercept in this situation mean that Jerry was given $75 for his birthday
The equation below is a linear equation.
y = 50x + 75
A linear equation is an equation that has a single variable raised to the power of 1. 50x is raised to the power of 1
75 represents the constant. This is the money he deposited in the account. 75 is the y-intercept. The y-intercept is the value of the line y when it crosses the y-axis
50x is the slope of the line. - 50 is the amount he puts in every month and x represents month.
The slope of a line also known as the gradient of the line determines the steepness and direction of a line. If the slope coefficient is less than zero, the slope is negative and it would decline from left to right
y is the dependent variable. It is the total amount he would have at the end of each month. y depends on the constant term (75), the number of months(x) and the amount he deposits every month (50)
at the end of :
one month, he would have : 50(1) + 75 = 125
two months, he would have : 50(2) + 75 = 175

2x-4y=14
3y+5x=9
Answers
Answer:
x=3, y=-2
Step-by-step explanation:
If 2x-4y=14, then we know that 2x=14+4y. This means that x=7+2y. If we substitute this into the next equation we get: 3y+(35+10y)=9. This means that we have 35+13y=9. If we subtract 35 from both sides we get 13y=-26. This means y=-2. If you subsitute this in the first equation, we have 2x--8=14. -- means + so you do 2x+8=14. This means that x=3.

Step 1: Define
5 - 7(2 - x) = 31 - 4(2x - 5)
Step 2: Solve for x
Distribute: 5 - 14 + 7x = 31 - 8x + 20Subtract/Add: -9 + 7x = -8x + 51Add 8x on both sides: -9 + 15x = 51Add 9 to both sides: 15x = 60Divide 15 on both sides: x = 4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5 - 7(2 - 4) = 31 - 4(2(4) - 5)(Parenthesis) Multiply: 5 - 7(2 - 4) = 31 - 4(8 - 5)(Parenthesis) Subtract: 5 - 7(-2) = 31 - 4(3)Multiply: 5 + 14 = 31 - 12Add/Subtract: 19 = 19Here we see that 19 does indeed equal 19.
∴ x = 4 is the solution to the equation.
what is the dividend yield on Stock A that sells 15$/share, when company A pays a quarterly dividend of $0.15 per share
Answers
Answer: The dividend yield on Stock A = 0.04
Step-by-step explanation:
Given: quarterly dividend = $0.15 per share
Annual dividend per share = 4 x 0.15 = $0.6 [1 year = 4 quarters]
Stock's price per share = $0.15
The computation of dividend is given by :-
Dividend yield = (annual dividend per share) divided by (the stock's price per share).
Here, Dividend yield = (0.6) ÷ 15 = 0.04
Hence, the dividend yield on Stock A = 0.04

Answer:
Linear measures (measures of length and width) are at a scale of 1:500; or
for every "real life" yard, the map would be "1/500" yard long.
Thus for measures of area, such as hectares, the map would would be 1/(500)² as big.
So: (3/5 = .6) hectares would be .6/(500)² hectares = .0000024 hectares.
And since 1 hectare = 15500031 in²;
the area on the map would be 15500031 (.0000024) in² ~ 37.2 in² ~ 240 cm²

A worker is stacking boxes.One stack has boxes that are 2 inches high. The other stack has boxes that are 5 inches high. At what height will the two stacks of boxes be equal in height?
Answers
Answer:
10 inches.
Step-by-step explanation:
One stack has boxes that are 2 inches high, then the height of this stack can be only multiples of 2 inches.
The other stack has boxes that are 5 inches high, then the height of this stack can be only multiples of 5 inches.
The height of both stacks will be the same for all the common multiples of 2 and 5.
Because 2 and 5 are prime numbers, all the common multiples between 2 and 5 will be direct products of these two numbers.
Like 2*5 = 10
is both a multiple of 2 and 5 (is the first common multiple)
Then we can use stacks of 10 inches.
Such that, for the stack where each box is 2 inches high, we need:
10in/2in = 5
5 boxes.
And for the stack where each box is 5 inches high, we will need:
10in/5in = 2
2 boxes.

A = 1/2(a+b)h solve for b
Answers
Answer:
2A/h - a = b
Step-by-step explanation:
Using A= 1/2(a+b)h
Divide both side by h
⇒A/h = 1/2(a + b)
Mutiply both sides by 2
⇒2A/h = a + b
Take the 2 over to the other side
2A/h - a = b
Keep in mind, that the (a) is not on the bottom, rather on its own
How much grain can this container hold? Use 3.14 to approximate your pi. Round your answer to the nearest hundreth
Answers
Answer:
953.78in^3 of grain
Step-by-step explanation:
You use the equation π r^2 h to find the volume of the cylinder
r = radius of the base = 9/2
= 4.5 in and the height h = 15 in
the volume is 3.14 * 4.5^2 * 15
= 953.78 in^3.
The amount of grain can this container hold is 953.78 inch³, So option 'B' is the correct answer to the following question.
Volume of cylinder based problem:What information do we have?
Diameter of cylinder = 9 in
Radius of cylinder = 9 / 2 in
Radius of cylinder = 4.5 in
Height of cylinder = 15 inch
Volume of cylinder = Amount of grain can this container hold
Amount of grain can this container hold = πr²h
Amount of grain can this container hold = (3.14)(4.5)²(15)
Amount of grain can this container hold = 953.78 inch³
Find our more information about 'Volume'.

Step-by-step explanation:
The way that I would do this is by plugging in 2 values for x, double it then see what happens
Let's say 2
So when we plug in 2 for x we get
5*2=y
y=10
Then what happens when we double x?
Our new equation would be 10x
*we get this becase 5*2=10*
so we plug in to for y=10x and get y=10*2 which is 20. Our answer doubled and therefore the answer is A
Let's do the same thing for number 2 with the number 10
5/10=.5
Then when the value of x triples our new equation is 5/3x
we use this formula and get 5/(3*10)=5/30=1/6=.1666667
This is equal to dividing it by 3 which means the answer is D
