If x = the width of the rectangle, which of the following equations is used in the process of solving this problem?

2x2 + 3x - 119 = 0
3x2 + 3x - 119 = 0
6x2 - 119 = 0

Answer 8

They give us that the width is x. They also give that the length is 3 more than twice the width.

\[W = x\]
\[L = 2x + 3\]

\[A =WL\]

\[A = x(2x + 3)\]

\[A = 2x^2 + 3x\]

Hey also gave us the area of the rectangle, which is 119.

\[119 = 2x^2 + 3x\]

\[0 = 2x^2 + 3x - 119\]
