Last week, Justin drove m miles. This week, he drove 209 miles. Using m, write an expression for the total number of miles he drove in the two weeks.

The total number of miles Justin drove in the two weeks can be expressed as m + 209.

so whats the answer

The expression for the total number of miles Justin drove in the two weeks is m + 209.

To write an expression for the total number of miles Justin drove in the two weeks, we can add the number of miles he drove last week (m) and the number of miles he drove this week (209). So the expression would be:

Total number of miles = m + 209

Note that the value of 'm' is not given, so we cannot simplify the expression further without additional information.
