The additive inverse of a number is important because it helps you to understand how to cancel terms for variables in equations and formulas.
Distribute the first set of parenthesis
<span><span>15<span>r<span><span>2</span><span></span></span></span>−20r+6r−8</span><span>
Combine like terms
</span><span><span>15<span>r<span><span>2</span><span></span></span></span>+(−20r+6r)−8</span><span>
Simplify your answer
</span><span>15<span>r<span><span>2</span><span></span></span></span>−14r−8
*Answer is </span>15r^2−14r−8*<span><span>
</span></span>

Answer:
Choice B and Choice C
Step-by-step explanation:
Hello! This is how I solved this question:
(10 x 8 x 2) + (3 x 3 x 4) = 160 + 36 = 196ft^3
(10 x 3 x 2) + (5 x 4 x 2) = 60 + 40 = 100ft^3
(8 x 4 x 2) + (3 x 6 x 2) = 64 + 36 = 100ft^3
(8 x 10 x 3) + (4 x 5 x 2) = 240 + 40 = 280ft^3
Choice B and Choice C are the same values, and knowing that you need two of the same values for the volume of the figure must be the same. Giving you your two answers from simply multiplying and adding the answers.
Hope this helps, don't hesitate to ask if you have additional inquiries!
