Properties and Expressions Quiz

What property is used to show the equivalent expressions below:

(3y + 2x) + 4x = 3y + (2x + 4x)

• Associative Property (changes the grouping)

• Commutative Property (changes the order)

• Distributive Property

• Identity Property

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

Use the Commutative Property of Addition to complete the equivalent expression:

2b + 7 + 5a² = 5a² + 2b + __

• 7b

• 7

• 7a²

• 5

Which property is represented?

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

• Commutative Property

• Associative Property

• Distributive Property

Use the Distributive Property to write an expression equivalent to:

9(x + 7)

• 9x + 7

• 9x + 63

• 72x

• x + 63

Write an equivalent expression using the Distributive Property:

(b + 8)5

• b + 40

• 5b - 40

• 5b + 40

• 5b + 8

Write an equivalent expression using the Distributive Property:

5(2x - 11)

• 10x - 11

• 10x - 55

• 7x - 16

• 10x + 55

Which of the following expressions is equivalent to:

10x + 70 ?

• 2(5x + 70)

• 5(2x + 70)

• 7(2x + 10)

• 10(x + 7)

Which of the following expressions is equivalent to:

24 - 18x ?

• 6(4 - 3x)

• 6(4 - 18x)

• 3(6 - 6x)

• 3(8x - 6)

Simplify the expression by combining like terms:

2x + 1 + 7x + 5 + x

• 10x + 6

• 16x

• 9x + 6

• 10x + 4
