Andy added 70 to 5 instead of multiplying 70 by 5.

Step-by-step explanation:

We have been given that Mrs.Ruiz bought 5 bags of balloons for a party. Each bag contained 70 balloons. Andy said Mrs.Ruiz bough a total of 75. Andy is incorrect what error did Andy make when calculating the total number of balloons.

To find the total number of balloons in 5 bags, we will multiply number of balloons in each bag by 5.

Therefore, the total number of balloons in 5 bags would be 350 balloons.

Andy added 70 to 5 instead of multiplying 70 by 5.

answer is 67%

step-by-step explanation:

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
