i need help with these problems thanks (:
1. (x + 2y) * 6x-y)
2. (5x - 9)^2
3. (x-4) (x^2 - 5x + 7)
4. ( 3x +1) - ( 4x -2)
5. 8x(x^2 + 4x - 9)

Integral of : 3*pi*x^(2/3) * [ ( x^(2/3) + 1 ) / x^(2/3) ]^(1/2)
Thanks in advance,-Note that:
∫ 3πx^(2/3)√{[x^(2/3) + 1]/x^(2/3)} dx
= 3π ∫ x^(2/3)√[x^(2/3) + 1]/x^(1/3) dx.
At this point, we can s

Ramona is a travel agent. She receives a 6% commission on vacation package sales.
How much commission will Ramona make if she sells $3,600 in vacation packages?-Set it up like this:6=x
1003600
Then
(dx)2x+1/(x+2)^4(x-1)^4
=(dx)2x+1/[(x+2)(x-1)]^4
= (dx)2x+1/(x^2 + x -2)^4
put t = x^2 + x -2
=> dt = ( 2x + 1 )dx which is the numerator!
=>integral (dx)2x+1/(x+2)^4(x-1)^4
= integral dt/t^4
