The missing longth is (Simplify your answer.)

Answer 1

Missing side = 30

Explanation:

13x - 1 = x - 1 +4x + 4

13x - 1 = 5x - 3

8x = 2

x = 4

Replace (x - 1) and (4x +4) with the x that we just found. It should equal 3 and 20. Then replace the x in (13x - 1). It should equal 53. Then subtract 53 - 23.
