What are the like terms in the expression? \( 4 m-9+3 n+2 \) -9 and 2 -9 and \( 3 n \) \( 4 m \) and \( 3 n \) \( 4 m \) and -9

In the expression \( 4 m - 9 + 3 n + 2 \), the like terms are those that share the same variable or are constant numbers. Here, \( -9 \) and \( 2 \) are like terms because they are constants, while \( 4 m \) and \( 3 n \) are not like terms since they have different variables. The correct answer focuses exclusively on constants. To combine them effectively, start by simplifying the constants. Combine \( -9 \) and \( 2 \) to get \( -7 \). This helps tidy up the expression to \( 4 m + 3 n - 7 \). When tackling expressions, always remember to group like terms together for clarity and ease of computation!
