There are several combinations to this question:5 and 197 and 1711 and 13
To find the sum of the numbers 9, -11, and 15, you add them together: (9 + (-11) + 15). First, (9 - 11 = -2). Then, (-2 + 15 = 13). Therefore, the sum is 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
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.
There are several combinations of odd numbers that add up to 43. For example, 3 + 29 + 11 is equal to 43, so is 5 + 27 + 11, and many more. In fact, if you allow negative numbers, you have an infinite number of combinations.
Add them up. The factors of 9 are 1, 3 and 9. The sum of the factors is 13.
