Iate 2/5 of my pizza what percent did i eat ?

Step-by-step explanation:

You ate 40%. I know this because you need to make the denominator one hundred. 5 times 20 equals 100. You then mulyiply 2 by 20 because you have to do the same for both. Then that is 40/100 which equals 40%.

you're missing vital information, add to it so we can solve this problem for you.

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
