Applying the distributive property from the right side, (5y - 3)7

The video tutorial covers the basics of multiplication, emphasizing the commutative property. It explains the distributive property and highlights common mistakes students make, such as combining unlike terms. The tutorial uses examples like 'five horses minus three chickens' to illustrate why unlike terms cannot be combined. It concludes with a practical application of the distributive property, ensuring students understand how to multiply terms correctly. The lesson is briefly interrupted by a fire alarm test announcement.

What is the result of applying the distributive property to the expression 3 * (Y + 5)?

• 3Y + 8

• Y + 15

• 3Y + 5

• 3Y + 15

Why can't you combine 5Y and 3 as like terms?

• Because they have different coefficients

• Because they have different variables or constants

• Because they are not both constants

• Because they are not both variables

If you have 5 horses and subtract 3 chickens, what is the result?

• 8 animals

• 2 horses

• 2 chickens

• 5 horses minus 3 chickens

What is the correct application of the distributive property in the expression 7 * (5Y - 3)?

• 5Y - 21

• 35Y - 21

• 35Y + 21

• 7Y - 3

When applying the distributive property, what should you be cautious about with negative terms?

• Ignoring them

• Changing their sign

• Multiplying them separately

• Ensuring they are included in the multiplication
