16x -2

Step-by-step explanation:

You know how to compute the perimeter of a rectangle of length L and width W:

P = 2(L+W)

Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.

P = 2((5x-2) +(3x+1))

P = 2(8x -1)
