Weight Lifting 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?

Answer:

Expression: 6x + 30

Explanation:

2[x + (x + 5) + (x + 2(5))]

2[2x + 5 + x + 10]

2(3x + 15)

6x + 30

The second question's terminology is too ambiguous for me to answer, apologies.
