• Distributive, Commutative, and Identity

• Distributive, Commutative, and Associative

• Identity, Associative, and Distributive

What is the main task given in the lesson?

• To memorize mathematical formulas

• To learn about new mathematical properties

• To identify equivalent expressions

• To solve a complex equation

How is the expression 6(x + 4) simplified?

• By dividing 6 by x

• By subtracting 4 from 6

• By multiplying 6 by x and 4

• By adding 6 and 4

Why is expression B not equivalent to 6x + 24?

• Because 6 multiplied by 24 is not 24

• Because 6 multiplied by x is not 6x

• Because 6 added to 24 is not 24
