Question 304755
I would say selection d (all positive numbers.


A minus times a minus will always give you a plus, so the answer has to be positive.


The selections for positive numbers are:


selection d and selection e.


I can't think of a situation where the result would not be positive, so selection d is good.


The only other possible answer would have to be selection e, and only if that answer gives a more accurate representation of the answer.


Selection e says all positive numbers less than 1.


That can be violated very easily.


If we let m be equal to -100 which is less than -1, and we let n = -.5 which is greater than -1, then the result would be equal to:


-100 * -.5 which would equal 50 which is greater than 1.


Selection e is not valid for all values of m or n so selection d has to be the answer.
