So the expression for the length in terms of the width would be w+7? And the inequality (b) would be 2(w) + 2(w+7)? Or...?

Yes, length is w + 7.

Inequality: 2w + 2(w+7) > 62
Becuase it says in the problem that the perimeter is more than or greater than 62.

Now you go ahead and solve that inequality (treat it like an equation, just leave > sign).

Solve as in find what w means? This is mainly the part I am confused on. I'm not quite sure how to solve it either. Although I've looked over the lesson many times.
