The volume of water and a rectangle swimming pool can be modeled by the function v(x)=x^3+13x-210. If the depth of the pool is given by the expression x-3, what are the expressions that represent the width and length of the pool?

Required,

Step-by-step explanation:

Given volume and depth respectively,

and

To find length and width of the rectanglular swiming pool we know,

Volume=lengthheightdepth.

Let depth=D=x-3, length=L, width=W, then

After divide we will get with remainder -144.

Thus,

Now to find root of,

Thus,

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
