Answer:

The value of x is 12.

Step-by-step explanation:

Given that perimeter is found when all sides are added together. So we can assume that all side lengths add together will give you 134 imches :

$x + 2x + 5 + 6x - 17 + 3x + 2 = 134$

$12x - 10 = 134$

$12x = 134 + 10$

$12x = 144$

$x = 144 \div 12$

$x = 12$
