the 1st one is right but you messed up the sign a number can't be greater than 6 and less the -2.so the answer is: -2(less or equal than)x(less or equal than)6

the 2nd one...you have to break it down by two different
the 1st break down is (x+2)(greater or equal than)1 the brackets mean absolute value
when you solve this one you get -3(less or equal than)x(less or equal than)-1
the 2nd break down is (x+2)(less or equal than)4
when you solve it, you get -6(less or equal than)x(less or equal)2
now you look for the common between these two you will find -6(less or equal than)x(less or equal than)-3(u) 1(less or equal than)x(less or equal than)2
