Q. Which expression is equivalent to 9(4z)9(4z)?\newlineChoices:\newline(A) 4z+94z + 9\newline(B) 36z36z\newline(C) z+13z + 13\newline(D) $z + \(36\)
  1. Apply Distributive Property: To find the equivalent expression for 9(4z)9(4z), we need to apply the distributive property of multiplication over addition.
  2. Multiply Numbers: First, we multiply the number outside the parentheses by the number inside the parentheses. 9×4z=36z9 \times 4z = 36z
  3. Compare with Choices: Now, we compare the result with the given choices to find the equivalent expression.\newlineThe result 36z36z matches choice (B) 36z36z.
