When you distribute a positive sign to a parentheses, you essentially change nothing. So, you can drop all of the parentheses for this entire equation. Now combine like terms.

$-4p^2-3p-17$

$-1(4p^2+3p+17)$

A homeowner wants to build a circular patio. if the diameter of the patio is 20 feet, what is its area to the nearest whole numb

We are asked to find the area of patio. It is circular so formula used for area is given by:
$A= r^{2} \pi$
Where
r = radius = diameter / 2 = 20 / 2 = 10 feet

$A = 10^{2} \pi =100 \pi$
When we round this to the nearest whole number:
$A =100 \pi = 314.159=314ft^{2}$
