Q. Which expression is equivalent to 9(d+2)9(d + 2)?\newlineChoices:\newline(A) 18d18d\newline(B) 11d11d\newline(C) 18d+918d + 9\newline(D) 9d+189d + 18
  1. Distribute 99: Step 11: Distribute 99 to both terms inside the parentheses.\newlineCalculation: 9(d+2)=9⋅d+9⋅29(d + 2) = 9 \cdot d + 9 \cdot 2\newline= 9d+189d + 18
  2. Compare with choices: Step 22: Compare the result with the given choices.\newlineCalculation: The expression 9d+189d + 18 matches choice (D).\newlineCheck: (D) 9d+189d + 18 is the only choice that fits the calculation.
