15 x 2
10 x 3
factors of 30 that add to 17 are 2 and 15
The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.
Supplementary angles add up to 180° → supplementary to 30° is 180° - 30° = 150°. Complementary angles add up to 90° → complementary to 30° is 90° - 30° = 60°.
It is impossible for three prime numbers less than 30 to add up to 1955. After all, 30+30+30 is only 90.
None add up to 30; you would need at least three 6-sided die with numbers 6-11 to add to 30.
The factors of 30 that add up to 9 are 3 and 6. When you multiply these two numbers, you get 30 (3 x 10 = 30), and when you add them, you get 9 (3 + 6 = 9). Therefore, the pair of factors that meet the criteria are 3 and 6.
The factor pairs of 30 are (30,1)(15,2)(10,3)(6,5) None of them add up to 20.
-30 and -30 -30 + -30 = -60 -30 x -30 = 900
