Question

Which expression represents the area of the rectangle?

(X+3)(4x-7)

Answer 1

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 2

Answer:

$4x^2+5x-21$

Step-by-step 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 $4x^2+5x-21$.
