Problema Solution

Janelle wants to enlarge a square graph that she has made so that a side of the new graph will be 1 inch more than twice the original side s. What trinomial represents the area of the enlarged graph?

Answer provided by our tutors

Area = length * width

length = width = s + 1

Area = (s + 1)(s + 1) = s2 + s + s + 1

= s2 + 2s + 1
