To find two numbers that multiply to -10 and add up to -9, we need to consider the factors of -10. The factors of -10 are (-1, 10), (1, -10), (-2, 5), and (2, -5). Among these pairs, (-1, 10) is the pair that adds up to -9. Therefore, the two numbers are -1 and 10.
2 x 10 = 20 2 + 10 = 12
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors 1+3+5+10=19, 1+2+6+10=19, 1+3+15=19, and 3+6+10= 19.
