The complete question is added as an attachment
The perimeter is calculated as:
P = 3x - 5 + 2x-3 + 15 - x
Evaluate
P = 4x + 7
The perimeter is 35.
So, we have
4x + 7 = 35
This gives
4x = 28
Divide by 4
x = 7
Substitute x = 7 in 3x - 5, 2x-3 and 15 - x
3x - 5 = 3* 7 - 5 =16
2x-3 = 2* 7 - 3 = 11
15 - x= 15 - 7 = 8
Hence, the value of x is 7 and the lengths of the sides are 16, 11 and 8
