Answer:

8x-2

Step-by-step explanation:

l = x+4

w = 3x-5

The perimeter is

P =2(l+w)

   = 2(x+4+3x-5)

Combine like terms

   = 2(4x-1)

Distribute

   = 8x-2

Answer:

8x-2

Step-by-step explanation:

The perimeter of a rectangle is 2L + 2W, where L represents the length and W represents the width. In this scenario, L is equal to x + 4 and W is equal to 3x - 5. We can setup an equation:

2(x+4)+2(3x-5)

We can then multiply x - 4 by 2 to get 2x+8

We can then multiply 3x - 5 by 2 to get 6x-10

Adding them together, we get the answer as 8x-2
