Factors are multiplied, not added. The question needs to be something like, "Which two factors of thirty add up to 11?" The answer would then be 5 and 6.
Factors multiply, like 1 x 11. Addends add, like 5 and 6.

no 11 is not a perfect number because when u add the factors the don't add up to 11

15 and 4 are the factors of 120 that add up to 19.
To find factors that add up to 240 and also add up to 140, we need to solve a system of equations. Let's represent the two factors as x and y. We have the equations x + y = 140 and x + y = 240. By solving this system, we find that the factors are 100 and 140.
