Rodrigo added 2 9 and 4 9 using these steps. 1. Check for common denominators. 2 9 and 4 9 2. Write the sum. 2 9 + 4 9 3. Add the numerators. 2 + 4 9 = 6 9

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: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

they would have to work 32 hours.

the answer is 3/2 and for decimal: 1.5
