You're original equation has a -81, so the factored form will have to have a positive and negative multiplying one another to achieve that...
f(x) = x(x + 9)(x - 9)
So,
"at least" means that is the minimum acceptable amount. So we will use the "greater than or equal to" symbol.
Let "w" represent the width of the traffic lane.
w ≥ 12 ft.

Step-by-step explanation:
The wording is all you need, you don't even need to do the math.
Answer: D
Step-by-step explanation: You just have to take the equation in the question and simplify it. -2 x y = -2y, -2 x -8 = +16, so -2y + 16, then on the other side add 10 to 15 15+10=25, and then keep the -y, so finally the final equation/inequality is -2y + 16 <u><</u> 25 - y.
