Not sure what the question is but
x^2 + 3x + 2 = (x + 2)(x + 1)
this is because 1lb is equal to 0.0625oz
So he knows there are definitely 66 trouts as he caught and tagged them.
The next day he caught 52, but 13 of them were already tagged, so were part of the number of trout he caught before.
So he can expect that:
66+(52-13)= 105 trout are in the lake
The answer is G because none of them can be divided by 6 besides 24
hope i helped:)
