By definition, 3 side lengths are a triangle if any 2 side lengths add up to be greater than the third.
We can already see that the side lengths 6 and 12 will add up to a value of 18, which is equal to the last side length, meaning that the three values are not a triangle.
(Since this is not true, this is not a triangle)
Hope this helps.

For a fixed total number of boys and girls, there is only one possible answer. The boys to girls ratio is 3:2, which means 3/5 are boys and 2/5 are girls. If the total number of boys and girls is N, then
number of boys = (3/5)N
number of girls = (2/5)N
Obviously, N must be a multiple of 5, since we cannot have "fractional" boys or girls.
