Can anyone help?

I have a few problems on my math I need help with.

( the little ^ means its an exponent)

(h^2+1) divided by (2h^4 - h^3 + h^2 + h - 3)

A word problem im having trouble with is

The area of a trianle is 15x^4 + 3x^3 + 4x^2 - x - 3 sqaure meters. The length of the triangle is 6x^2 - 2 meters.

one other problem is

(using a variable)

choose a number and mutliply by 3

then add the sum of your number and 8 to the product you found

now divide by the sum of your number and 2

what number will the volunteer always have at the end. Explain?

I got

3x+(x+8) divided by 2.

but it doesnt make sense
