The formula for volume of this rectangular prism is: v=2x^3+17x^2+46x+40 find an expression for the missing side length. show all of your work for full credit.

the missing side length is

Step-by-step explanation:

we know that the volume of the rectangular prism is equal to

In this problem we have

using a graphing tool find the x-intercepts of the function

see the attached figure

The x-intercepts are

so

therefore

the missing side length is

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
