a camera car with a crane is used to film a movie. the crane's max. height is 18ft and the min. height is 4ft. write a compound inequality that describes the possible heights of the crane.
18≥x≤4

Reiny
What you want to express is that the height is between 4 and 18.
Usually the same inequality sign is used with the smaller on the left and the larger on the right, thus
4 ≤ height ≤ 18 , or 4 ≤ x ≤ 18 if you want to use x
