Could someone help me solve these problems? That would be great. If you could start them, I could finish them or something.

(x+7)^2 / x-7 divided by x^2-49 / 7x-49. Solve and simplify.

3 + 9/y-6 over y + 9/y-6. Simplify.

x+7 / x^2-4x-45 + x+3 / x^2-7x-18. Solve and simplify.

2a / a+1 = 7 / a+6. Solve for a.

3x^2+8x+5 / x+1. Simplify.

3 divided by the sum of x and 4 equals the quotient of 5 and the difference of x and 4. Find x.


Thank you for any help!

I learned how to do this on Friday but I completely forget. >____<;
The question says: Determine if each equation has the same slope as the equation y = 2x - 4.
One of the equations is y = -2x + 3.

I don't want to just know the answer.. I need to know how to do the process, so I can show my work.

Thank you! C:

I know there was a lot of the 'drugs, sex, and rock and roll', but what about the LEGAL activities? I know roller disco was big, but were there a lot of cars or was everyone into walking/biking/taking public transport everywhere?

How big were drive in theatres, fishing, skateboarding, yoga, hanggliding, stuff like that? What did kids do for fun in the 1970's? What about schooling? Did a lot of kids want to go to college/university? was it open to both men and women?

Any help on education and activities during the 1970's would be appreciated, thanks! :)
