Q. Select the expressions that are equivalent to 9n+8n9n + 8n.\newlineMulti-select Choices:\newline(A) 7n+11n7n + 11n\newline(B) 17n17n\newline(C) n+8n+8nn + 8n + 8n\newline(D) 12n+4n12n + 4n
  1. Combine like terms: Combine like terms in the expression 9n+8n9n + 8n.\newlineCalculation: 9n+8n=17n9n + 8n = 17n
  2. Compare with choices: Compare the result with each choice to find equivalent expressions.\newlineCalculation: \newline(A) 7n+11n=18n7n + 11n = 18n\newline(B) 17n=17n17n = 17n\newline(C) n+8n+8n=17nn + 8n + 8n = 17n\newline(D) 12n+4n=16n12n + 4n = 16n
