I have the velocity of v(t)= -t +8 when t is greater than 6 and less than or equal to 11. I need to know the distance function f(t) that corresponds to the v(t).

I also have the velocity of v(t)= 3t-36 when t is greater than 11 and less than or equal to 12. I need to know the distance function f(t) that corresponds to the v(t).

Thanks.

Write the following in interval notation

3 / (x+10) - 6 / x^2+12x+20 > 0
(3 over x plus 10, minus 6 over x squared plus 12x plus 20 is greater than or equal to 0)

I got as far as factoring out the common denominator, (x+10)(x+2) and ended up with 3x/(x+10)(x+2) > 0

Is that the wrong form, the wrong answer, or both?

Any help is appreciated.

If you can provide steps, great, if you give the answer, I can just figure it out, I'm decently intuitive.
