Pre Algebra Quiz #4 Properties and Simplifying Expressions

Which property is being described?

15y + 7x = 7x + 15y

Moving the terms around does not change the value.

• Associative Property

• Identity Property

• Commutative Property

• Distributive Property

Which property is represented?

7(2t + u) = 14t + 7u

• Commutative Property

• Associative Property

• Distributive Property

Write an equivalent expression using the Distributive Property:

(b + 8)5

• b + 40

• 5b - 40

• 5b + 40

• 5b + 8

Simplify the expression:

7v + 12 + 2v - 2

• 23v

• 19v

• 9v + 10

• 9v + 14

Are these expressions equivalent?

(4 x 5) x 7 = 4 x (5 x 7)

• Yes because of the commutative property

• Yes because of the associative property

• Yes because of the distributive property

• No, they are not equivalent.
