Answer:
B) f(g(x)) = 15x² + 18
Step-by-step explanation:
Plug the entire equation of g(x) in for the x in f(x)
f(g(x)) = 5(3x² + 3) + 3
f(g(x)) = 15x² + 15 + 3
f(g(x)) = 15x² + 18

Step-by-step explanation:
Volume of a triangular prism is: 
We are given the base of 5, the length of 12, and the height of 8. All measurements are in meters.

The volume of the prism should be 240 square meters.
Take h common:
h(B + r) = 25
Divide b+r
h = 25/ b + r
Subtract bh:
hr = -bh + 25
Divide h:
r = -bh/h + 25/h
Simplify:
r = -b + 25/h
Hope this helps!
