If x and y are integers such that (x+1)^2 is less than or equal to 49 and (y-1)^2 is less than 64, what is the sum of the maximum possible value of xy and the minimum possible value of xy? Choose one:
A) -16  B) -14  C) 0  D) 14  E) 16
(x+1)^2 &lt;= 49   x &lt;= 6   x &gt;= -8   (y-1)^2 &lt; 64   y &lt; 9   y &gt; -7   Max possible value of xy is -8 × -6 = 48   minimum possible value of xy is -8 × 8 = -64   -64 + 48 = -16   -16nswer : -16
