Best ResponseYou've already chosen the best response.0No, not exactly. So you're trying to figure out if g and k are positive or negative. So you're right, g would be negative. so that eliminates two answers, C & D, right?

Best ResponseYou've already chosen the best response.11) when two negative terms are added, they remain negative. 2) when two negative terms are multiplied/divided, they become positive. 3) when two negative terms are subtracted, then it depends which one is larger .
