Answer:
f(x) = x³ + 10x² + 27x + 18
Step-by-step explanation:
Given the zeros x = - 3, x = - 6 and x = - 1
Then the factors are (x + 3), (x + 6), (x + 1)
and the polynomial is the product of the factors, that is
f(x) = (x + 3)(x + 6)(x + 1) ← expand the first 2 factors using FOIL
= (x² + 9x + 18)(x + 1) ← distribute
= x³ + 9x² + 18x + x² + 9x + 18 ← collect like terms
= x³ + 10x² + 27x + 18
4x + 8y = -24
- 4x - 4x
8y = -4x - 24
8 8
y = ⁻¹/₂x - 3
Answer:
979.68in²
Step-by-step explanation:
3.14× 6² =226.08
3.14× 6×40 = 753.6
753.6 + 226.08 = answer stated above
He could have wrote -2.5 or -3.
The would be A if I remember correctly
