inequality check
x2(greater than and equal to) 4
= 2 (greater than and equal to) x (greater than and equal to) 6
is this correct? thanks u
and
1 (less than or equal to)  x + 2  (less than or equal to) 4
= 1 (less than or equal to) x (less than or equal to) 2
correct? thank u

inequalities
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
