Best ResponseYou've already chosen the best response.0But do you have the result somewhere to double check for me?

Best ResponseYou've already chosen the best response.0The way I did it is: 28zx/(z7x)(z+7x) + z7x/z+7x Explanation: (z7x) with z7x are reduced...you just cross them out and then you just add them together 28zx remains alone on the top si on the bottom we have z+7x + z+7x which equals 2z+14x so that's why I came up with the answer as being 28zx/2z+14x. It would've been good to know if you had the response somewhere at the end of the book so we can double check the answer.

Best ResponseYou've already chosen the best response.0Nope, that's no the right answer. It can be done though..., that's all I know for now.

Best ResponseYou've already chosen the best response.0mowrey almost had it right to begin with. When you cancel don't forget the 1that is there when you cancel

Best ResponseYou've already chosen the best response.1I get an answer of (z+7x)/(z7x). Here is how I arrived at the answer: 28zx/(z^249x^2) + (z7x)/(z+7x) Factor the bottom left term to get: 28zx/(z7x)(z+7x) + (z7x)/(z+7x) Now find a common denominator to get: [(28zx + (z7x)(z7x)]/(z7x)(z+7x) (28zx+z^214zx+49x^2)/(z7x)(z+7x) (z^2+14zx+49x^2)/(z7x)(z+7x) Factor the top term to get: (z+7x)(z+7x)/(z7x)(z+7x) = (z+7x)/(z7x)
