CPM Homework Help : CCG Problem 8-76

If the rectangles below have the same area, find $x$ . Is there more than one answer? Show all work.

Two shapes. The first is a square with 2, x, labeled on one side. The second is a rectangle. The base is labeled, x plus, 10. The height is labeled, 2, x, minus, 3.

Hint:

If the areas are the same, how can you set up an equation to solve for $x$ ?

More Help:

Based on this equation, can there be two answers?
Remember with the area of a rectangle being $\text{base}\times\text{height}$ , you end up with $\left(2x\right)\left(2x\right)=\left(x+10\right)\left(2x-3\right)$ .
