Q. Which expression is equivalent to 7(r+7)7(r + 7)?\newlineChoices:\newline(A) 49r49r\newline(B) 7r+497r + 49\newline(C) 14r14r\newline(D) 49r+749r + 7
  1. Distribute 77: Distribute the 77 to both terms inside the parentheses.7(r+7)=7×r+7×77(r + 7) = 7 \times r + 7 \times 7
  2. Calculate products: Calculate the products.\newline7×r=7r7 \times r = 7r\newline7×7=497 \times 7 = 49
  3. Combine results: Combine the results from Step 22.\newline7(r+7)=7r+497(r + 7) = 7r + 49
