There are several combinations to this question:5 and 197 and 1711 and 13
The 13 interior angles add up to 1980 degrees
The 13 interior angles of a 13 sided polygon add up to 1,980 degrees
It is 42
There are 13 combinations.
6 + 7 = 13(Sum means add)
When you add 8 and 5 the sum will be 13. On the other hand when you add 6 and 7 the sum will be 13. That's why it's equal to 13.
The sum, meaning you add them together. 7+5=13.
It is: 13
Let 'N' be the number. The sum of the number and 13 is (N+13).The square of the sum of the number and 13 is (N+13)2N2 + 26 N + 169.It's probably easier to add 13 to the number and then square that answer ... less arithmetic.
The three odd numbers that add up to 43 are 13, 15, and 15. This is because 13 + 15 + 15 = 43. These numbers are odd because they are not divisible by 2, and their sum equals 43, satisfying the condition of the question.
Add them up. The factors of 9 are 1, 3 and 9. The sum of the factors is 13.
