Q. Which expression is equivalent to 3(7z)3(7z)?\newlineChoices:\newline(A) 7z+37z + 3\newline(B) z+21z + 21\newline(C) 21z21z\newline(D) z+10z + 10
  1. Calculate Product: Calculate the product of 33 and 77.\newline3×7=213 \times 7 = 21
  2. Apply Distributive Property: Apply the distributive property to the expression 3(7z)3(7z).3(7z)=(3×7)z=21z3(7z) = (3 \times 7)z = 21z
