What is the perimeter of a rectangle with a length of 3x + 3 and a width of x - 1

P = 8x+4

Step-by-step explanation:

The perimeter of a rectangle is found by using the formula

P = 2 (l+w)

We know l = 3x+3 and

w = x-1

Substitute these values in

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

Combine like terms

P = 2 (4x+2)

Distribute the 2

P = 8x+4
