Answer:
x=3
6x-3 = 15
Step-by-step explanation:
The sides with the lines means they are the same length
The perimeter is
6x-3 + 6x -3 + 32 = 62
Combine like terms
12x+26=62
Subtract 26 from each side
12x+26-26 =62-26
12x =36
Divide by 12
12x/12 = 36/12
x = 3
The missing side length 6x-3 = 6*3 -3 = 18-3 = 15
