Answer:
33
Step-by-step explanation:
We know that PS and QR are the same size since we are working with parallel sides of a parallelogram. We can write an equation and solve for z.
5z + 3 = 6z - 3
~Subtract 3 to both sides
5z = 6z - 6
~Subtract 6z to both sides
-z = -6
~Divide -1 to both sides
z = 6
Now, find the length of QR with what we found for z.
6z - 3
6(6) - 3
36 - 3
