Question

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

Answer 1

Answer::

2x2 + 6x − 20

Step-by-step explanation:

Answer 2

The area of the rectangle is
`5x^(2) -18x-8`

Step-by-step 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`
