I could really use your help on a couple of problems that I'm having trouble on...

Simplify each rational expression. Write answers with excluded values.
1.) 6d^2c/3c
 
4.) x^2-x/(x-1)(x+7)
 
Multiple. Write answers with excluded values.
 
2.)4/3a^2bc*6bc/8w
 
3.)(w-9)(w-3)/(w+2)(w+1)*(w+2)(w-11)/(w-9)(w-11)
 
(don't worry only two left...sorry for all of these...)
 
Divide. Write answers with excluded values.
 
5.)14k^3v/v^2-4÷7ky^4/v^2+4v+4
 
9.)(d-3)(d^2+3d+9)/d+1÷d(d-3)/(d-9)(d+1)
 
Again, I'm sorry for asking help on so many...you don't have to explain how you got your answers, I'll figure that out myself.
