Need help With math Urgently!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

(.............. is just spacing so I could set the problems up)

Identify horizontal and vertical asymptotes
1)
.......... - x^3
f(x) = -------------
......... x^3 - 8


Divide the two Expresions and simplify the result.

2)

x^2 + 8x - 20 ....... x^2 + 9x
------------------- / -------------------
5x^3 + 50x^2....... x^2 + 7x -18

Simplify the following Rational Expressions
3)

n^2 + 2n - 24
--------------------
n^2 - 11n + 28

4)

x^3 + 4x^2
---------------
x^2 -16

5)

x^2 - 4x +4
----------------
....15x
------------------
... x - 2
------------
..... 5x

Multiply the Expressions, simplify the result.
6)
........... x^2 + 4
(x - 4) * -----------
........... x^2 - 64


7)

2y^2 ......12x
------ * --------
3 ..........5y

If you put just one or two questions per post, people are more likely to answer since they will not feel like they are doing your homework for you. I was going to! ☺
