Think of this as being a tightrope for Cecil to cross. How would you describe his path using this picture?
2x + 1 or x + 1 + x
This problem is very similar to part (a).
If the lengths labeled ''m'' were instead labeled as ''1'', how would you write the expression?
3m + 5 or m + m + m + 5
Use parts (a) and (b) as guides if you are having trouble.
Remember that the variable represents a number, so you
can use it in an expression just as you would a number.
