Question

Sorry for the questions, I am taking Algebra 1 a year early and am a bit confused, this lesson is using the distributive property.

Answer 1

We are adding like terms for this question. We combine same variables (ex. 5x+8x or 195xy+4xy) and all constants (without variables ex. 5+196).

So the side lengths are 5+x, 5+x, and xy.

We need to added them up for perimeter.

5+x+5+x+xy

Simplify

xy+2x+10

This would be the simplifies form.
