140
-10 and 2 -12 and 4 -20 and 12
The factors that multiply to 120 and add up to -8 are -12 and 10. This is because when you multiply -12 and 10, you get -120, and when you add them together, you get -8. Thus, the pair of factors you are looking for is (-12, 10).
-1, 6 and -12.

-10 and 2 -12 and 4 -20 and 12
The factors that multiply to 120 and add up to -8 are -12 and 10. This is because when you multiply -12 and 10, you get -120, and when you add them together, you get -8. Thus, the pair of factors you are looking for is (-12, 10).
-1, 6 and -12.
144. You divide 120 by 5 since 20 is one fifth of 100 percent. You will end up with 24. You then add it to the original number, 120, and you get 144.

To find factors that add up to 240 and also add up to 140, we need to solve a system of equations. Let's represent the two factors as x and y. We have the equations x + y = 140 and x + y = 240. By solving this system, we find that the factors are 100 and 140.
