(4x + 7) feet. Write and simplify a linear expression for
the perimeter.

Answer 1

2(5x- 2) + 2(4x+ 7); (18x+ 10)

Explanation:

Answer 2

Explanation:

A rectangle has a length of (5x - 2) feet and a width of (4x + 7) feet. Write and simplify a linear expression for the perimeter.

when:

L = (5x - 2)

W = (4x + 7)

P = 2L + 2W

P = 2(5x - 2) + 2(4x + 7)

P = 10x - 4 + 8x + 14

P = 18x - 4 + 14

P = 18x + 10
