h=-16t^2+148t+30
find the derivative:
h = -32t+148
0 = -32t+148
-32t=-148
t = -148/-32 = 4.625 seconds
h=-16(4.625)^2+148(4.625)+30 = 372.25
height = 372.25 feet, time = 4.63 seconds

Answer:
x^2 +2xy + 2xz - y^2 + z^2
Step-by-step explanation:
(x+y+z) (x-y+z)
x^2 + xy + xz + xy - y^2 + yz + xz - yz + z^2
x^2 + xy + xy + xz + xz - y^2 + yz - yz + z^2
x^2 +2xy + 2xz - y^2 + z^2
