Answer: B) Distributive Property
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.
