Answer 5

You know it's going to be a positive number and an negative number since when they are multiplied you get a negative number.

Answer 6

And you know the absolute value of the positive number will be greater than the absolute value of the negative number since it's a positive number when added.

Answer 7

yes I know, ive been working on these two questions and Im stuck

Answer 8

Ok, there actually aren't two numbers that add to get 28 and multiply to get -60.

Answer 9

That's what my teacher is askng

Answer 10

the other one is sum of 56 and product of 300

Answer 11

The first one is 30 and -2

Answer 12

Here are all of the possible ways to multiply 2 whole numbers to get -60

1*(-60) = -60
2*(-30) = -60
3*(-20) = -60
4*(-15) = -60
5*(-12) = -60
6*(-10) = -60
(-1)*(60) = -60
(-2)*(30) = -60
(-3)*(20) = -60
(-4)*(15) = -60
(-5)*(12) = -60
(-6)*(10) = -60

You then make a table of all the sums of the pairs (see attached)
