Find two factors of 28 with a sum of 11.
is it 1,2?
Find the prime factorization of 330?
is it 3, 110? 
Scooby, for #1, do 1 and 2 add to 11 as the problem states?
For #2, isn't 110 divisible by something, say 2? 
i don't understand how to do these sorry
so would the answer for #1 be 5 and 6 or 7 and 4? 
Well, lets see. We want two factors of 28 that add to 11. Your answer of 7 and 4 gives 28 if multiplied and 11 if added. 6 and 5 gives 11 if added but not 28 if multiplied. So....
