A weight lifter puts an x-pound weight on each side of a bar. A weight 5 pounds heavier than the first is then added to both sides. Finally, a weight 5 pounds heavier than the second weight is added to both sides. The expression 2[x + (x + 5) + (x + 2(5))] models the total weight lifted. Simplify the expression. What would the expression be if each added weight was 10 pounds heavier than the previous weight?
