Hagrid had 3 1/2 feet of orange ribbon. He used some ribbon to make a bow for a gift. Now he has 1 3/8 feet of ribbon left. How much ribbon did Hagrid use?

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

answer:

125 yards

explanation:

75+50=125. that is my answer

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
