The area (in square inches) of a rectangle is given by the polynomial function A(p) = p2 + 9p + 20. If the length of the rectang

Answer:

$Width = p + 4$

Step-by-step explanation:

Given

$Area = p^2 + 9p + 20$

$Length = p + 5$

Required

Determine the width

The area of a rectangle is:

$Area = Length * Width$

This gives:

$p^2 + 9p + 20= (p+5)* Width$

Expand

$p^2 + 4p + 5p + 20= (p+5)* Width$

Factorize

$p(p + 4) + 5(p + 4)= (p+5)* Width$

$(p + 5) (p + 4)= (p+5)* Width$

Divide both sides by p + 5

$p + 4= Width$

$Width = p + 4$

99 X 99 X 99 / 9 - 99 /99 PLEASE EXPLAIN ;)

charle [14.2K]

Answer:

107810

Step-by-step explanation:

You can use the order of operations! So we start with 99^3/9. That is 99^2*11. So now let’s do 99/99, it’s 1. So 99^2*11 is 107811, so the answer is 107810.
