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

Dmitrij [34]

Answer:

The correct answer is b. 116,900

If you divide the amount htat the company paid for the rights by the net value you can find the total number of copies that the company has to sell to break even.  

# books = $725,000/$6.20 = 116935 or approximately 116900 copies of the book.
