Please help I only have two questions left!

Question

anonymous · Answer

4|k + 5| > 8

anonymous · Answer

Let N = {x|x is a multiple of 2} and P = {x|x is a multiple of 6}. Describe the intersection of N and P.

phoenixfire · Answer

$$4\left| k+5 \right|>8$$$$\left| k+5 \right|>{8\over 4}$$Now because of absolute you have to account for positive and negative. So you solve for k in the following: $$k+5>2$$$$k+5<-2$$

What about the second question?

phoenixfire · Answer

I'm not entirely sure, but the description of the intersection will be {x | x is a multiple of 2 and x is a multiple of 6} but when x is a multiple of 6 it is also a multiple of 2, so i guess the final set that results would just be {x | x is a multiple of 6}
But I'm probably wrong on this one.
