Step-by-step explanation:

Hello There!

The first thing we want to do is find how much money we earn for washing 1 car

To do so we divide 5 (amount of cars washed) by the money we made from washing those 5 cars

35/5=7

so every car we wash we make 7 dollars

now we multiply the amount of money we make washing one car by 4

4x7=28

so we would earn $28 for washing 4 cars

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

i got 142 as my answer
