Question

Okay so,
I got part A,B,C done, need help with Part D.
Medal and Fan.

Answer 1

Create expressions to represent the dimensions of the pool.
(3 + 3w)(w)(2l – 7)
Create a variable to represent the width of the pool. Determine the expressions to represent length and the depth in terms of the width variable.
w - (3 + 3w)
2(3 + 3w) - 7
Determine the polynomial expression to represent the area of land space that the pool will cover.
Area = L x W
Area = (3 +3w) w
Area = 3w^2 + 3w
Using the area and the depth expressions, determine the polynomial expression that is used to represent the volume.
Volume = L x W x D
Volume = A x D
Volume = (3w^2 + 3w) [2(3 + 3w) - 7]
Volume = (3w^2 + 3w) (6w- 1) (like terms)
Volume = 18w^3 – 15w^2 – 3w

PART D Classify the volume polynomial by degree and number of terms.
