Which expression is equivalent to the expression (-mn2 + 2n2 - 6m2n) + (2mn2 - 2n2 + 3m2n)?
A
mn2 – 3mn
3 mm2 - 40²
3m2n - mn2
mn2 + 4n2 - 9m?n

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
