Answer:
A
Step-by-step explanation:
Given
(x + 2)³
= (x + 2)(x + 2)(x + 2) ← expand second/third factor using FOIL
= (x + 2)(x² + 4x + 4) ← distribute
= x(x² + 4x + 4) + 2(x² + 4x + 4) ← distribute both parenthesis
= x³ + 4x² + 4x + 2x² + 8x + 8 ← collect like terms
= x³ + 6x² + 12x + 8 → A
(x + 2)(x + 2)(x + 2)
(x^2 + 4x + 4)(x + 2)
x^3 + 4x^2 + 4x + 2x^2 + 8x + 8
Simplify
Solution: x^3 + 6x^2 + 12x + 8
The answer is A

Answer:
8.49
Step-by-step explanation:
6^2 + 6^2 = 72
√72 = 8.485... = 8.49
F(11) means to replace x in the equation with 11
12(11) + 5
12 x 11 = 132
Now you have 132 + 5 = 137
F(11) = 137
