the answer is 4x^2+5x-21, you multiply x by 4x, then x by -7, 3 by 4x and 3 by -7, you simplify and here you go :)

Answer:


4x^2+5x-21

Explanation:

We have been given the length an width of a rectangle. We are asked to find the area of the rectangle.


(x+3)(4x-7)

Using FOIL, we will get:


x(4x-7)+3(4x-7)


4x^2-7x+12x-21


4x^2+5x-21

Therefore, the area of the rectangle would be
4x^2+5x-21.
