Best ResponseYou've already chosen the best response.2and change division to multiplication ( multiply top with the reciprocal of the divisor ) \[\large\rm \frac{ a }{ b } \div \frac{ c }{ d } = \frac{ a }{ b } \times \frac{ d }{ c}\]

Best ResponseYou've already chosen the best response.0I have a really, really hard time with the parentheses in these problems. Do they change operations at all?

Best ResponseYou've already chosen the best response.0I know, but once it is factored, I have a problem using them in division problems. I'm working on the problem and I'm almost done. Would you check my answer when I'm done?

Best ResponseYou've already chosen the best response.0After switching around everything I had (A4)(a+3)/2(a=3) times (a+3)(a1)/2(a4). I cross multiplied 2(a4) and (a4)(a=3) to get (a+3)^2 and cross multiplied the other values to get 2(a1) Then distributed.

Best ResponseYou've already chosen the best response.2so (a4)(a+3) = (a+3)^2 ?

Best ResponseYou've already chosen the best response.0That's what I got when I multiplied it by 2(a4) The a4s cancelled out and that left 2 and a+3. I suppose it could have been 2(a+3,) though.

Best ResponseYou've already chosen the best response.2i just want to know how u got (a+3)^2 ?? :)

Best ResponseYou've already chosen the best response.2yep right (a4)s cancels out :)

Best ResponseYou've already chosen the best response.0I multiplied the value (a4)(a+3) by 2(a4). When the a4s cancelled, I was left with 2 on one side and a+3 on the other. So, reevaluating, it wouldn't be (a+3)^2 it would be 2(a+3)

Best ResponseYou've already chosen the best response.0I'm not cheating :( I'm just trying to confirm what I think is right before my test times out. I am trying!
