Answer 2

Let's simplify the expressions you provided:

1. 39 + 42 + c: Adding 39 and 42 gives 81. Therefore, the expression simplifies to 81 + c.

2. 39 + c + 42: Rearranging the terms, we have c + 39 + 42. Adding 39 and 42 gives 81. Therefore, the expression simplifies to c + 81.

3. 73 + c + 72 - 9: Adding 73, c, and 72 gives 145 + c. Subtracting 9 from 145 + c gives 136 + c.

So, the simplified expressions are as follows:

1. 39 + 42 + c = 81 + c
2. 39 + c + 42 = c + 81
3. 73 + c + 72 - 9 = 136 + c
