Q. Which expression is equivalent to 4k+3k4k + 3k?\newlineChoices:\newline(A) k+7k + 7\newline(B) 7k7k\newline(C) 6k6k\newline(D) k7k^7
  1. Identify like terms: Identify like terms in the expression 4k+3k4k + 3k. Both terms contain the variable kk, so they are like terms and can be combined.
  2. Add coefficients: Add the coefficients of kk. 4+3=74 + 3 = 7. So, 4k+3k=7k4k + 3k = 7k.
  3. Match with choices: Match the result with the given choices. The expression 7k7k corresponds to choice (B)(B).
