Emily volunteered at an animal shelter for a total of 119 hours over 6 weeks. estimate the number of hours she volunteered each week.

round 19 in 120 to the nearest tenth cause the tenths place is bigger than 5 19 = 20   so  120 divided by 6=20

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

no not all of them.

step-by-step explanation:

some of them have a square base.
