Answer:
B
Step-by-step explanation:
Given
f(x) = 3(x + 1)(x - 7) ← expand the factors using FOIL
= 3(x² - 6x - 7) ← distribute the parenthesis
= 3x² - 18x - 21 → B
Yes the equation is linear because the linear equation is y=mx+b and y=85x-600 is linear.

V = L * W * H
= 15 * 12 * 10
= 1800
= 12 * 6 * 3
= 216
= 1800 + 216
= 2016
Hope that helps and you can remember the formula and steps for future use!
