Best ResponseYou've already chosen the best response.0You guys how is this teaching and how is this learning? Please try to teach @Makayla43 and not just give the answer. And @Makayla43 you shouldn't be just looking for answers. I think freckles here was trying to teach you how to do this.

Best ResponseYou've already chosen the best response.0number that up to c and product is b coefficient. It is more important to show why it works then how to do something that is mostly guess work.
