write a simplified polynomial expression in the standard form to represent the area of the rectangle below x-4 5x+2

Ann [662]

The area of the rectangle is $5x^{2} -18x-8$

Explanation:

One side of the rectangle is $x-4$

The another side of the rectangle is $5x+2$

The formula to find the area of the rectangle is length × width

Area = length × width

Substituting the values, we have,

$\begin{aligned}\text { Area } &=(x-4)(5 x+2) \\&=5 x^{2}+2 x-20 x-8 \\&=5 x^{2}-18 x-8\end{aligned}$

Thus, the area of the rectangle is $5x^{2} -18x-8$
