Simplifying Expressions with Like Terms and Distributive Property

The video tutorial begins with feedback on the previous video and introduces a more soothing approach. It explains the simplification of expressions using the distributive property, starting with a basic example of 2(3x + 5) and moving to a more complex expression 7(3y - 5) - 2(10 + 4y). The tutorial emphasizes understanding the distributive property and combining like terms to simplify expressions.

What does the expression 2(3x + 5) represent?

• None of the above

• Two separate expressions of 3x added to 5

• The sum of 3x and 5, doubled

• The product of 2 and 3x added to 5

What property is used to simplify the expression 2(3x + 5)?

• Identity property

• Commutative property

• Associative property

• Distributive property

What is the result of distributing 2 in the expression 2(3x + 5)?

• 6x + 5

• 5x + 10

• 6x + 10

• 3x + 10

How do you interpret the expression 7(3y - 5)?

• Subtract 5 from 3y, then multiply by 7

• Multiply 7 by 3y and add 5

• Add 7 to 3y then subtract 5

• None of the above

What is the result of distributing 7 in the expression 7(3y - 5)?

• 21y - 25

• 10y - 35

• 21y + 35

• 21y - 35

How is the expression -2(10 + 4y) simplified?

• -20 - 8y

• -20 + 8y

• -8y + 20

• 8y - 20

What is the final simplified form of the expression 7(3y - 5) - 2(10 + 4y)?

• 21y - 55

• -13y - 55

• 13y + 55

• 13y - 55

What does combining like terms in the expression 7(3y - 5) - 2(10 + 4y) result in for the 'y' terms?

• -13y

• 29y

• 5y

• 13y

What is the combined numerical value after simplifying -35 and -20?

• 15

• -55

• -15

• 55

Which property is primarily demonstrated in the video to simplify algebraic expressions?

• Multiplicative identity property

• Commutative property

• Associative property

• Distributive property
