3 if other people do your homework... you can't learn... maybe if you asked people how to HELP you do it.. then i would.. however, for #27 where it says "m=" whenever you see a problem like that.. substitute it into the equation, for instance..m=6 there for 2(6) = 12 then add 15 and you'll have your answer. |
