1)) Which expression is equivalent to \( 5(3 w) \) ?

The expression \( 5(3w) \) can be simplified by using the distributive property. When you multiply 5 by 3w, you actually multiply the coefficients together: \( 5 \times 3 = 15 \). So, the equivalent expression is \( 15w \). Another way to think about this is to visualize it as having 5 groups of \( 3w \), which totals \( 15w \). It's like having 5 sets of 3 apples, resulting in a juicy total of 15 apples!
