Answer:
PR = 2*36 = 72
SU = (1/2)54 = 27
RS = 36
Step-by-step explanation:
By the Midpoint Theorem, the argent that connects midpoints of the sides of a triangle equals half the parallel side. That said, 
- PR is the full side that corresponds to midpoint segment TU. Therefore it's twice the distance of TU.
- SU is the midpoint segment that corresponds to fill side PQ and therefore half the distance.
- RS is half the the length of PR since S is the midpoint.
 
        
             
        
        
        
This problem is a difference of squares. So to solve this you want to factor it out so you get two numbers that multiple to -9 and add to 0. That would be -3 and 3
f(x)=(x-3)(x+3)
So your solution when you set f(x) to 0 would be -3 and 3.
