Find the roots of the factored polynomial.
(x+9)(x–9)
Write your answer as a list of values separated by commas.

-9,9

Step-by-step explanation:

To find the roots, we set this equal to zero

(x+9) (x-9) =0

Using the zero product property

x+9 =0      x-9=0

x =-9             x=9

On the diagram you can see the box plot represents the number of minutes customers spend on hold at a company. Here are three main quartiles (three vertical lines, two of them are vertical sides of rectangle (at 3 and 6) and one - interior segment at 5):

The upper quartile of the data is

correct choice is C.
