Answer 1

help please!

Answer 2

you are being asked how many integers are between \(-2\) and \(4\) not including those two.
count them
btw i think there is a typo here. are you being asked for \(n(A)\)?

Answer 3

oh no that is not right. what does \(n(B)\) mean ?

Answer 4

question is very unclear
the solution set is \(\{-1,0,1,2,3\}\) the rest is not clear at all
