Question 286362
If {{{(x - 7)(y + 7) < 0}}}, then either {{{x-7<0}}} (ie {{{x-7}}} is negative) or {{{y+7<0}}} (ie {{{y+7}}} is negative), but not both. If they are both negative, then the result is positive. Also, if they're both positive, then the product is positive.



So if {{{x-7<0}}}, then {{{x<7}}} which is choice C)



and if {{{y+7<0}}}, then {{{y<-7}}} which is is choice B)



So the answers are B and C (if you're allowed multiple answers), but not at the same time. If you aren't allowed multiple answers, then there's a typo somewhere.
