You are finding the perimeter, which has double of each side length given.

Note: P = perimeter

2(5x - 1) + 2(2x + 1) = P 

Distribute 2 to each monomial in the given parenthesis

2(5x - 1) = 10x - 2
2(2x + 1) = 4x + 2

10x - 2 + 4x + 2 = P

combine like terms.

P = 10x + 4x - 2 + 2
P = 14x

C) 14x, is your answer

hope this helps
