3. That looks like the same question as two I can't quite see it.
Answer:
We have been given that Charles has six times as many action figures as Ben
Let Ben has x action figures
So according to question Charles will have 6x.
together the action figures total more than 75



So Ben will have more than
action pictures.
And 

Charles will have more than
.
Answer:
Step-by-step explanation:
- cotx cos x - cot x = 0
- cotx( cosx - 1) = 0
1. <u>cotx = 0</u>
- x = π/2 + πn
- In the interval [0, 2π] we have π/2 and 3π/2
2. <u>cosx = 1</u>
- x = 0 + 2πn
- In the given interval we have 0 and 2π
<u>So the solution set is:</u>
