Answer:
14. x=30, y=15, z=165
15. x=10, y=25
Step-by-step explanation:
It is in the air 5.625 seconds.
Using the quadratic formula,

0 is when the ball is first launched, 5.625 is when it hits the ground again.
perimeter =QR+RS+ST+TU+UQ =26.1
RQ = 5.39
RS = 4.47
ST = 3.61
TU = 4.12
UQ = 8.54
The answer is going to be c because 12-35=23 and since there is variables you have to add the variable.
