Simplifying an expression using distributive property ex1, 4(x + 2)

The video tutorial explains the distributive property, which states that a number outside parentheses can be distributed to each term inside via multiplication. The teacher demonstrates this by rewriting an expression and simplifying it using the distributive property, resulting in a simplified expression.

What does the distributive property allow you to do with a number outside the parentheses?

• Multiply it with each term inside the parentheses

• Subtract it from the terms inside the parentheses

• Add it to the terms inside the parentheses

• Divide it by each term inside the parentheses

In the expression 4 * (X + 2), how would you apply the distributive property?

• 4X + 2

• 4 + X + 2

• 4 * X + 4 * 2

• 4 * (X + 2)

What is the result of multiplying 4 by X in the expression 4 * X + 4 * 2?

• 4

• X

• 4X

• 8

What is the simplified result of 4 * 2 in the expression 4 * X + 4 * 2?

• 2

• 4

• 8

• 6

What is the final simplified form of the expression 4 * (X + 2) using the distributive property?

• 4X + 2

• 4X + 4

• 4 + X + 2

• 4X + 8
