Answer:
Step-by-step explanation:
8 - 24k + 1 = -25 - 7k
-24k + 9 = -25 -7k
-17k + 9 = -25
-17k = -34
k = 2
answer is D

Step-by-step explanation:
Firstly, we'll try to simplify the integrand. By hint 1, we see that:

Simplifying the integrand gives us:

Next, by hint 2, we observe that:

So this tells us to make the substitution: 
Doing so gives us:
, which should be trivial.
