Question

20. The side of a square is 2x + 8 inches long. The perimeter of the square

is 20x + 8 inches. What is the side length of the square in inches?

Answer 1

12

Explanation:

Since its a square, all the sides are the same.

(2x+8)4=20x+8

8x+32=20x+8

32-8=20x-8x

24=12x

x=2

2x+8= 2(2)+8= 12
