Examples of the Distributive Property

Oct 13, 2025 by recoveryshake.com 126 views

The distributive property is a fundamental concept in mathematics that allows us to expand expressions by multiplying each term inside the parentheses with the factor outside. It is a crucial property that helps us simplify complex expressions and solve equations. In this article, we will explore the distributive property and identify which of the given expressions demonstrates this property.

What is the Distributive Property?

The distributive property states that for any real numbers a, b, and c, the following equation holds:

a(b + c) = ab + ac

This means that we can distribute the factor a to each term inside the parentheses, b and c, and then combine the results.

Examples of the Distributive Property

Let's consider some examples to illustrate the distributive property:

2(3 + 4) = 2(3) + 2(4) = 6 + 8 = 14
5(x + 2) = 5x + 10
3(2y - 4) = 6y - 12

As we can see, the distributive property allows us to expand expressions by multiplying each term inside the parentheses with the factor outside.

Which Expression Demonstrates the Distributive Property?

Now, let's examine the given expressions and determine which one demonstrates the distributive property:

A. $3 + 4 + 5 = 4 + 3 + 5$

This expression does not demonstrate the distributive property. It is simply a commutative property, which states that the order of the terms does not change the result.

B. $-2(5 + 7) = -2(7 + 5)$

This expression does not demonstrate the distributive property. It is simply a commutative property, which states that the order of the terms does not change the result.

C. $3(-8 + 1) = 3(-8) + 3(1)$

This expression demonstrates the distributive property. We can see that the factor 3 is distributed to each term inside the parentheses, -8 and 1, and then combined the results.

D. $6[(7)(-2)] = [(6)(7)](-2)$

This expression does not demonstrate the distributive property. It is simply a commutative property, which states that the order of the terms does not change the result.

Conclusion

In conclusion, the expression $3(-8 + 1) = 3(-8) + 3(1)$ demonstrates the distributive property. It shows that the factor 3 is distributed to each term inside the parentheses, -8 and 1, and then combined the results. This is a fundamental concept in mathematics that helps us simplify complex expressions and solve equations.
