<h3>Answer: 10 and -8</h3>

The coefficients are the numbers to the left of the variable terms

10b is one variable term with the coefficient 10

-8a is the other variable term with the coefficient -8

The terms 2 and 6 are constants as they don't have any variables multiplied with them.

Answer:

252

Step-by-step explanation:

The order of the books isn't important, so we'll use combinations.

The number of ways to choose 5 books from 10 is:

₁₀C₅ = 10! / (5! (10 − 5)!)

₁₀C₅ = 10! / (5! 5!)

₁₀C₅ = 10×9×8×7×6 / (5×4×3×2×1)

₁₀C₅ = 252

volume of cylinder=π r²h=π(3)²×18=162 π cm³

volume of sphere=4/3 π(3)³=36 π cm³

reqd. empty space=162 π-3×36π=54 πcm³
