If -4 < x < 7 and -5 < y < 3, which of the following specifies all the possible values of xy? Pick one:
A) -42 < xy < 21
B) -42 < xy < 24
C) -28 < xy < 18
D) -24 < xy < 21
E) -35 < xy < 20
The least value of xy is a bit more than 7*(-5)=-35 and the largest value of xy is a bit less than (-4)*(-5)= 
<gadget id="calculator">(-4)*(-5)</gadget>
<output>20</output>
20.   Therefore -35 &lt; xy &lt; 20.   Answer: -35 &lt; xy &lt; 20.
