Answer:
-25/4 = u
Step-by-step explanation:
-3u-17=(u+8)
Add 3u to each side
-3u+3u-17=(u+3u+8)
-17 = 4u +8
Subtract 8 from each side
-17-8 = 4u+8-8
-25 = 4u
Divide by 4
-25/4 = 4u/4
h = 64 feet
If you graph the function you see that 64 feet is the maximum of the parabola so this is the max height that the projectile reaches.
5x+28=7x-4
5x+32=7x
32=2x
x=16
