If w and t are positive integers, wt + w + t cannot be Choose the correct choice from the following choices:
A) 5
B) 6
C) 7
D) 8
E) 9
Let wt + t + w = x   Add 1 on both sides:   wt + t + w + 1 = x + 1   t(w + 1) + w + 1 = x + 1   (w + 1)(t + 1) = x + 1   Minimum value of (w + 1) = 2   Minimum value of (t + 1) = 2   Hence x + 1 cannot be prime   Substitute x from the given options:   6 + 1=
