Which expression is equivalent to \( 2 w ? \) \( 2 w+w \) \( 2 w+w \) \( 2 w+2 \) 2

To simplify, notice that \(2w + w\) combines like terms. Since \(w\) is essentially \(1w\), adding these together gives you \(3w\). So, \(2w + w\) is not equivalent to \(2w\) but actually represents a greater quantity. On the other hand, expressions like \(2w + 2\) and \(2\) do not contain \(w\) and thus are not equivalent either. Ultimately, none of the provided options is simply \(2w\). Keep in mind that expressions can often be simplified or manipulated in ways that reveal new relationships. When multiplying terms or combining like variables, seek the simplest form that retains the meaning of each component. Watch out for sneaky errors—like mistaking additions or forgetting to combine coefficients properly.
