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.
