Question

which of the following are reasonable answers for the product of two negatives and a positive? •20 •10 •-20 •-10

Answer 1

The product of two negatives and one positive will give you a negative number. Take the three numbers; -1, -1, and 1. There are two negatives and one positive. 
-1 x -1 x 1 = 1 x 1 = 1 = positive number
So the possible answers are the positive numbers:

20 and 10

Hope this helps :)

Answer 2

The correct answers are:

20 and 10.

Explanation:

Multiplying two negatives results in a positive product. Multiplying this positive product by another positive number will result in a positive answer. This means the only possible answers from our choices are the two positive ones, 20 and 10.
