Answer:
- 2x³
Step-by-step explanation:
f(x) - g(x)
= - x - (2x³ - - x) ← distribute parenthesis by - 1
= - x - 2x³ + + x ← collect like terms )
= - 2x³
Volume = Length x Length x Length
Volume :
(x + 2) (x + 2) (x + 2)
= (x² + 4x + 4)(x + 2)
= x³ + 2x² + 4x² + 8x + 4x + 8
= x³ + 6x² + 12x + 8
Answer: x³ + 6x² + 12x + 8
