8 < x < 12
12 < y < 15
if x and y are integers that satisfy the conditions above , what is one possible value of xy ?
Since x and y are integers,
$\displaystyle x=\{9,10,11\}$
$\displaystyle y=\{13,14\}$
So there can be six values of xy.
$\displaystyle xy=9\times 13$
or
$\displaystyle xy=9\times 14$
or
$\displaystyle xy=10\times 13$
or
$\displaystyle xy=10\times 14$
or
$\displaystyle xy=11\times 13$
or
$\displaystyle xy=11\times 14$
