If a postcard has the dimensions (x+13) inches by (x) inches with the area of 48 inches squared, state the quadratic equation that represents this, find the possible value(s) for x, and find the actual dimensions of the postcard.

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)
