12(x+3) is the factored answer
John exercised 20% more than Toby. So the number of hours that John exercises per week is 14 + 0.2(14) = 14 + 2.8 = 16.8.
Jenny exercises two more hours than John. So the number of hours that Jenny exercises per week is 16.8 + 2 = 18.8.
So an expression representing the number of hours that Jenny exercises after w weeks is 18.8w.

Answer:
Step-by-step explanation:
For this question, set u = arctan(x). This would be the easiest way because the derivative of arctan(x) is 
which is what we have. Before setting u, always look at the question and think about possible derivatives.
Next, plug in u and du.
(rearranging)
Substitute arctan(x) back in for u and add +C.
