Question

Hello, I need some help with this homework question please?HW Q3

Answer 1

We can divide the figure into two rectangles, as shown below

Therefore,

`A=A_(upper)+A_(lower)=(5x-3)(x+2)+(x+1)(3x-2)`

Simplify as shown below

`\begin{gathered} \Rightarrow A=5x^2+7x-6+3x^2+x-2=8x^2+8x-8 \\ \Rightarrow A=8x^2+8x-8 \end{gathered}`

Thus, the answer is 8x^2+8x-8, option B
