Question

Which of the following correctly uses the distributive property to multiply 12 and 9?

(10 x 10) − (2 x 1) = 100 − 2 = 98
(10 x 10) + (2 x 1) = 100 + 2 = 102
(10 x 9) − (2 x 9) = 90 − 18 = 72
(10 x 9) + (2 x 9) = 90 + 18 = 108

Answer 1

The distributive property is applied correctly to multiply 12 and 9 as (10 x 9) + (2 x 9) = 90 + 18 = 108.

Step-by-step explanation:

The correct use of the distributive property to multiply 12 and 9 is (10 × 9) + (2 × 9) = 90 + 18 = 108. In the distributive property, you break down one of the numbers into a sum of its parts, multiply each part by the other number, and then add the products together. Here, 12 is decomposed into 10 and 2, and each is multiplied by 9, then the results are added together.

Answer 2

(10 x 9) + (2 x 9) = 90 + 18 = 108

Step-by-step explanation:

This is the answer because you break 12 into different parts, multiply them separately multiply them with nine. You can check the answer by doing 12*9 = 108 which matches what we need.
