1)
Width = w
Length = 6 units greater than its width = w + 6
Area = L * W = w(w + 6) = w^2 + 6w
Answer is c) A = w^2 + 6w
2)
Canton was 7,720 and increase 80 per year = 7,720 + 80x
Holly Spring was 3,200 and increase 120 per year = 3,200 + 120x
If both populations are equal then the expressions of them must be equal so
Answer is
d) 7720 + 80x = 3200 + 120x
