Answer:
28
Step-by-step explanation:
f(6) = -3 * 6 + 10 = -18 + 10 = -8
g(f(6)) = g(-8)
g(-8) =
= 64 - 24 - 12 = 64 - 36 = 28

Answer:
960cm³
Step-by-step explanation:
Find the base of the triangle (use phytagoras theorem)
c²= a²+b²
20²= 16²+b²
400=256+b²
b²=400-256
b²= 144
b=

base= 12
Volume: (1/2×b×h)×l
= (1/2×12×16)×10
=(6×16)×10
=96×10
=960cm³
