If x is an integer, and 169 < x^2 <= 361, which of the following is the sum of all possible values of x?
Choices
A) 135  B) 124  C) None of the above  D) 105  E) 116
The range of x is from 14 .. to 19 and -14 to -19 so the sum is 0 hence ans None of the above, I guess, unless I am missing something!
