Correct answer: A.
Explanation: The Distributive Property states that a(b+c) = ab + ac.
Therefore, when applying this property to the problem 7(19), we can rewrite 19 as 10 + 9.
So, 7(10 + 9) = 7(10) + 7(9) = 70 + 63.
Now you try taking a multiplication problem apart.
You have to multiply 7 by 19. Which equation uses the Distributive Property to take this problem apart?
