15 and 4 are the factors of 120 that add up to 19.
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).
How about: 120+1.2 = 121.2
-1, 6 and -12.

-15+-8=-23 -15*-8=120
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.
No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime

120 + 138

for a regular hexagon, all angles would add up to 720 or each one is 120. for an irregular hexagon all the angles still add up to 720 but not all the angles, if any, will be 120
