The factors of 21 that add up to 8 are 1 and 7.
factors of 30 that add to 17 are 2 and 15
15 and 4 are the factors of 120 that add up to 19.
115
Add them up. The factors of 9 are 1, 3 and 9. The sum of the factors is 13.
15 + 15 + 5 + 5 + 3 + 1 = 44
584
44. 11*4=44 11+4= 15

It is 44. The reason is that 44 = 11 X 4 and 11 + 4 =15.
2 numbers that add up to 8
The answer is 50 because its factors are 1,2,5,10,25,50. When you add up the sum of 50 you get 5 which is a prime number. Also it is between 44 and 53. :)
The factors of 21 that add up to 8 are 1 and 7.
To factor a trinomial (three-term expression) of the form n2+bn+c, find the two numbers h and k that are factors of c and add up to b. Then, write those numbers in this template: (n+h)(n+k) For the trinomial n2+7n-44, c = -44 and b = 7. The two numbers that are factors of -44 and add up to 7 are 11 and -4. So, the factored form would be (n+11)(n-4).
None. Factors don't add, they multiply.
Factors multiply. The same set of numbers won't add up to both 140 and 240, but 120 and 20 are factors of 240 that total 140.
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.
