The area of the rectangle is [tex]5x^{2} -18x-8[/tex]
Explanation:
One side of the rectangle is [tex]x-4[/tex]
The another side of the rectangle is [tex]5x+2[/tex]
The formula to find the area of the rectangle is length × width
Area = length × width
Substituting the values, we have,
[tex]\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}[/tex]
Thus, the area of the rectangle is [tex]5x^{2} -18x-8[/tex]
