Answer:
Below.
Step-by-step explanation:
1/20 is a small distance needed to be traveled right?
20/20 is the whole length.
If 1/20 gets traveled in 3/4 of a second,
3/4x2- or 2(1/20) which equals one right?
20(3/4) = 15 seconds
2, 4 are the correct ones
3x - 9 - (6 / (x+4))
3x - 9
|----------------------------------------
(x +4) | (3x^2 + 3x - 42 )
3x^2 + 12x
------------------------------
-9x - 42
-9x - 36
-----------------------------------
- 6
Answer: 3x - 9 - (6 / (x+4))
