(r+3)/(r-2)=(r-1)(r+1)

(r+3)(r+1)=(r-1)(r-2)

r^2+4r+3=r^2-3r+2

7r=-1

r=-1/7

You are very welcome!

:P

It is around 27,295,538,859,730,818.34465860927220128658, or around twenty-seven quadrillion two hundred ninety-five trillion five hundred thirty-eight billion eight hundred fifty-nine million seven hundred thirty thousand eight hundred eighteen and thirty-four quintillion four hundred sixty-five quadrillion eight hundred sixty trillion nine hundred twenty-seven billion two hundred twenty million one hundred twenty-eight thousand six hundred fifty-eight hundred quintillionths.

why did i make myself suffer like that?

You are very very very very very welcome.

Not old for work yet ;)

Do math, jump in the pool, play videogames, play my cello, try to make time as slow as possible so that the next school year doesn't come by quickly

I would say around a year for the basics of everything but at least 3 if you really want to get in depth.

Parallel means that the lines never touch, and for that to happen, they must have the same slope.

The slope of -2 means that an equation is y = -2x+4. In fact, the y-intercept doesn't matter because they are all parallel.

You are very welcome!

:P

If the function is negative, the line is below the x-axis.

You can see that it is below on (-2

You are very welcome!

:P

CPhill is right, but (sqrt2)^3=2sqrt2.

You are very welcome!

:P

See alan's explanation

But to the nearest degree: 46 degrees

You are very welcome!

:P

I think we need a picture of the cone... If you could post it that would be great!
