Final answer:
The distributive property allows us to simplify expressions by multiplying each term inside the parentheses by the number outside the parentheses.
Step-by-step explanation:
The distributive property states that when you multiply a number outside the parentheses by a sum or difference inside the parentheses, you distribute the multiplication to each term inside the parentheses. In this case, you need to distribute the multiplication of 6x to both 8 and -1.
6x × 8 = 48x
6x × -1 = -6x
So, the expression 6x (8-1) can be simplified as:
6x (8-1) = 48x - 6x
Therefore, the missing term is 6x.
