2 likes2,378 views
The document discusses the distributive property rule in algebra where a(b + c) = ab + ac. It provides examples of using the distributive property to simplify multiplication, such as 3(40 + 2) and 6(x + 9). Practice problems are given applying the distributive property to expressions like -2(8 + 7) and -5(-5 - 5). The document also shows using the distributive property to combine like terms in expressions.
