Question

Someone help i need an answer

Answer 1

Remember that the formula for the perimeter of a rectangle is:

`2w + 2l`

• 
  `w` is the width of the rectangle
• 
  `l` is the length of the rectangle

Thus, in this case, you can see that we are adding two of the same monomials and two of another monomial. One monomial is
`x + 15` and another monomial is
`x + 5`. In this case, these monomials would fulfill the perimeter equation of a rectangle.

Applying this perimeter structure, we can find that this expression represents a perimeter equation of a rectangle with sides x + 15 and x + 5.
