Which expression is equivalent to \( 2 f+6 f \) ?

When you combine like terms in the expression \( 2f + 6f \), you simply add the coefficients of \( f \). So, \( 2 + 6 = 8 \). Therefore, the expression simplifies to \( 8f \). It's like collecting all your apples into one basket; instead of counting them separately, you just add them up! In practical scenarios like budgeting, combining similar expenses can help you get a clearer picture of your finances. For example, if you have $2 for one type of expense and $6 for another, pooling them together gives you a total of $8 for that category. This technique keeps things neat and organized!
