Can someone please help me with some simple math?
Simplify: (2x+10) divided by (x+1) all divided by (x^2 + 4x-5) divided by (10x-10).
(20x^2 – 100) divided by (x^3 + 5x -4)
1 divided by 5(x+1)
20 divided by (x+1)
12x divided by (x^2 +5x – 4)
* I get it down to 20x2+80x-100/ x3+5x2-x-5 and then I don't know what to do.
Find the slope of the following equation: 3x + 2y = 6
–3/2
2/3
3/2
-2/3
None of these
Please help!!!!

I hope this is the problem
(2x+10)/(x+1)
---------------------
(x^2 + 4x-5)(10x-10).
= (2x+10)/(x+1) X (10x-10)/(x^2 + 4x-5)
=(2x+10)(10x-10) / (x+1)(x^2 + 4x-5)
=(20x^2 -20x +100x -100) / (x^3 +x^2 +4x^2 +4x -5x -5)
=(20x2+80x-100)/(x3+5x2-x-5)
After this we will factorize num and denom
=20(x^2+4x-5)/ (x-1)(x^2 +6x +5)
= 20 (x+5)(x-1)/(x-1)((x+5)(x+1)
=20/(x+1)
slope 3x+2y =6
2y = 6-3x
y =3 -3/2x
slope = m = -3/2

all i know is that the slope is - 3/2

Oh man I wish I knew. I suck at math. That's why I ask for help on here too. Haha

school assignments...nope...no answers...
common man....do your thing...
give a little respect to your teachers...
