Answer:
a
Step-by-step explanation:
you have to find the hole volume of the other shapes.
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)
Answer:
Yes, they are equivalent.
Step-by-step explanation:
The surface area volume = l×b
or, 14×10 cm = 140 ans
The angles look like

F- angles are corresponding angles.
Corresponding angles are congruent.
