Caroline cut a square cake vertically to make two rectangle slices. Each rectangle had a perimeter of 57 inches. How long is each side of the original square cake?

The length of each side is 19 inches.

Step-by-step explanation:

So the square cake is cut in half which means two half sides would equal one whole side. SO, since the two "halves" in the smaller rectangle would equal one whole side, plus the two whole sides in the smaller rectangle, you would divide 57 inches by 3.

57 divided by 3 equals the quotient of 19. Thus, the answer is 19 inches.

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
