Answer:
Step-by-step explanation:
1 side = 2.5y - 3
8 sides = 8(2.5y - 3)

Answer:
(a)
Step-by-step explanation:
(f • g)(x) = f(x) × g(x), that is
(5x² + 2x - 3)(6x - 3)
Each term in the second factor is multiplied by each term in the forst factor, that is
5x²(6x - 3) + 2x(6x - 3) - 3(6x - 3) ← distribute all 3 parenthesis
= 30x³ - 15x² + 12x² - 6x - 18x + 9 ← collect like terms
= 30x³ - 3x² - 24x + 9 → (a)
