4n3 2m 6m 5n 2n should be written as {<span>4n^3, 2m, 6m, 5n, 2n}
4n^3 stands alone. No other term has this format.
2m and 6m are like terms and can be combined into 8m.
5n and 2n are like terms and can be combined into 7n.

Answer:
part a: -40 < x < 140
part b: open circles on both -40 and 140 with an arrow from each pointing inward. (towards zero). the solutions represent temperatures that will keep the gas in liquid form.
part c: it will freeze because -49 is less than -40, and therefore not a solution to the inequality.
explanation
a. x must be greater than -40 and less than 140 as outlined in the problem. so x > -40 and x < 140
b. open circles are non inclusive, and we do not include -40 or 140 because the gas will not be a liquid at those temps.
