Question

A patio has a length of 8 feet and a width of x + 2 feet . Write and expression in simplest form for the perimeter of the patio

Answer 1

2(x + 10)

Explanation:

The perimeter is all the sides added together so you times the length by 2, (8 × 2 = 16). Then the width by 2 ( 2 × (x+2) = 2x + 4) add them together

16 + 2x + 4

2x + 20

take out the highest common factor of 2

2(x + 10)
