Answer:

P = 10x + 12

Explanation:

The length of the rectangle is

L = 3x + 7

The width of the rectangle is

W = 2x - 1

The formula for perimeter of a rectangle is

P = 2L + 2W

Plug in the values for length and width and simplify.

P = 2(3x + 7) + 2(2x - 1)

P = 6x + 14 + 4x - 2

P = 10x + 14 - 2

P = 10x + 12
