Answer:
3x³ + 12x² - 7x - 28
Step-by-step explanation:
(f • g)(x) = f(x) × g(x)
= (x + 4)(3x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
x(3x² - 7) + 4(3x² - 7 ) ← distribute both parenthesis
= 3x³ - 7x + 12x² - 28
= 3x³ + 12x² - 7x - 28
Answer:
1) 23/2
2) 529/25
Step-by-step explanation:
Transformation:


A = 
-----------------------------
Transformation:

A = 
x = the granddaughter's age x + 2 = the grandson's age
x + x + 2 ≥ 12 Collect like terms.
2x ≥ 12 Divide both sides by 2.
x ≥ 6 years
x + 2 ≥ 8 years
