Q. Which expression is equivalent to 2d+7d2d + 7d?\newlineChoices:\newline(A) 9d9d\newline(B) 8d8d\newline(C) d9d^9\newline(D) d+9d + 9
  1. Combine like terms: Combine like terms by adding the coefficients of dd.2d+7d=(2+7)d2d + 7d = (2 + 7)d
  2. Perform addition of coefficients: Perform the addition of the coefficients.\newline(2+7)d=9d(2 + 7)d = 9d
