:confused: I am having major difficulties with my Alegebra, if anybody can help please hurry it's due soon! Here are my problems :

1. A triangle has three sides 3x+7, 4x-9 and 5x-6. Find the expression that represents its perimeter.

2. The quotient when 3 more than a number is divided by 3 less than that same number.

3.6x^2y^3+9x^2y^3

3x^2y^2

I am very confused and I have to be at work in a few hours so I need HELP ASAP!
