Answer 1

I hope this helps you

Answer 2

The question is what both experssions best represent in the context of the problem.

The expresssion x best represents the width of the rectangle.

The expression x + 12 best reprents the lenght of the rectangle.

This is because if you call x the width, then the length is 12 more than that, i.e. 12 + x.

If you wanted to solve the problem now you could write

2*(width + length) = perimeter

2(x + 12 + x) = 24 and solve for x.

But the answer to the question is:

x best represents the width of the rectangle.

x + 12 best reprents the lenght of the rectangle.
