A. r
You sure?
Apologies for the incorrect answer in my previous response. The correct answer is C. r + 5.
An expression is a mathematical phrase that contains variables, numbers, and operations but does not contain an equality sign (=) indicating an equation. In this case, r + 5 is an example of an expression because it includes the variable r, the number 5, and the addition operation, but it does not have an equality sign.
