What are the zeros of the polynomial function? f(x)=x^3+x^2−9x−9

Step-by-step explanation:

The zeros of a function are the values of x when f(x) = 0.

Factor left side of the equation.

Take (x+1) common.

Set factors equal to 0.

First possibility:

Second possibility:

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12
