A rectangle has a length of x and a width of 5x^3+4-x^2. What is the polynomial that models the perimeter of the rectangle

And the width for this case is:

And we know that the perimeter is given by:

And replacing we got:

And symplifying we got:

Step-by-step explanation:

For this problem we know that the lenght of the rectangle is given by:

And the width for this case is:

And we know that the perimeter is given by:

And replacing we got:

And symplifying we got:

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
