Q. Which expression is equivalent to 9(a+3)9(a + 3)?\newlineChoices:\newline(A) 27a27a\newline(B) 12a12a\newline(C) 9a+279a + 27\newline(D) 27a+927a + 9
  1. Distribute 99: Distribute the 99 to both terms inside the parentheses.9(a+3)=9×a+9×39(a + 3) = 9 \times a + 9 \times 3
  2. Multiply terms: Multiply 99 by aa and 99 by 33. \newline9×a=9a9 \times a = 9a\newline9×3=279 \times 3 = 27\newlineSo, 9(a+3)=9a+279(a + 3) = 9a + 27
