If x is an integer and x^2 < 37

the greatest possible value of x will be 6

the least possible value of x will be -6

the greatest possible value of x minus the least possible value of x 6+6 = 12

Hence D

Answer is choice D.

-6 & 6 are the least and greatest possible values of x. Hence difference of these two values is 12.

\(x^2\) yields positive values all time. we must consider both positive and negative values of x.

x ( highest ) = 6
x ( lowest) = -6.

greatest possible value = 6 - (-6) = 12.

D is the correct answer.

greatest value = 6
and least value = -6
so 6-(-6) = 12
IMO D

since x2<37
greatest positive value of x =6
Least value = -6
6-(-6)=12

The largest integer x could be is 6, and the smallest it could be is -6. So the difference is 6 - (-6) = 12.

Answer: D
