Alicia Oneal · Answer 1

Answer: B) Distributive Property

Step-by-step explanation:

Since, In The distributive property we can multiply a sum by multiplying each addend separately and then add the products.

For example, If we have a expression a (b+c) then by applying distributive property we can write, a (b+c) = ab+ac

Here, given expression, 4 (x - 6) + 12 = 20

Step 1. 4x-24 + 12 = 20 (by distributive property)

Step 2. 4x - 12 = 20 (By addition property of equality)

Step 3. 4x = 32

Step 4. x=8 (division property of equality)

Thus, the correct missing reason in step 1 is B) Distributive Property.
