Answer:

A. 22x-11

B. 121 cupcakes

Step-by-step explanation:

Part A:

The simplified form of the expression is

5(2x-4)+3(3+4x)

(10x-20)+(9+12x)

(10x+12x)+(9-20)

22x-11

Part B:

Put x=6 in the above simplified equation to get the number of cupcakes Mrs. Jones bake last week

22x-11

22(6)-11

132-11

121 cupcakes

The perimeter of a rectangular swimming pool is 160 feet . The length of the swimming pool is four times its width. Find the dim
Murrr4er [49]
Formula for Perimeter of Rectangle:

P = 2(L + W)

Plug in 160:

160 = 2(L + W)

L = 4W
So we can plug in '4W' for 'L' in the first equation.
<span>160 = 2(L + W)

160 = 2(4W + W)

Combine like terms:

160 = 2(5W)

160 = 10W

Divide 10 to both sides:

W = 16

Now we can plug this back into any of the two equations to find the length.

L = 4W

L = 4(16)

L = 64

So the width is 16, and the length is 64.</span>

HELP PLZZZ!!!! What is the approximate area of a circular pond?
Georgia [21]

Answer:

<h2>B. 49,062.5 ft²</h2>

Step-by-step explanation:

The formula of an area of a circle:

A=\pi r^2

r - radius

We have the diameter d = 250 ft. We know: d = 2r.

Therefore r = 250 : 2 = 125 ft.

Substitute:

A=\pi(125)^2=15625\pi

\pi\approx3.14\to A=(15625)(3.14)=49062.5\ ft^2
