What is the result of applying the distributive property to 2(x - 3)?

• 2x - 3

• 2x + 3

• 2x + 6

• 2x - 6

What is the expanded form of 5(x + 3)?

• 5x + 15

• 5x - 15

• 5x + 3

• 5x - 3

What is the simplified form of the equation after applying the distributive property?

• 2x + 6 + 10x = 5x + 15

• 2x - 6 + 10x = 5x + 15

• 5

• 10

• 20

• 15

What is the expanded form of 2(x - 3) + 10x?

• 2x - 3 + 10x

• 2x + 3 + 10x

• 2x - 6 + 10x

• 2x + 6 + 10x

Which property justifies the missing step in the equation?

• Identity Property

• Distributive Property

• Commutative Property

• Associative Property

What is the missing step in the equation?

• 2x + 6 + 10x = 5x + 15

• 2x - 6 + 10x = 15 + 5x

• 2x + 6 + 10x = 15 + 5x

• 2x - 6 + 10x = 5x + 15
