If u(u+v) does not equal 0, u > 0, is 1/(u+v) < (1/u) + v?
1. u + v > 0
2. v > 0

B.


1) U is positive but V can for example be -4. This would make the left bigger than the right equation. However, if v is 7, the right would be bigger than the left. Not Sufficient


2) Since V is positive and we already know U is positive, the left will always be less than the right. Sufficient.
