Ch.3 Test - Algebraic Expressions and Properties

Evaluate the expression when a = 6, b = 8:

a - 6

• -2
• 12
• 0
• 14

Evaluate the expression when a = 6, b = 8:

ab

• 14
• 56
• 24
• 48

Write the phrase as an expression:

twice a number x

HINT: there are two correct answers

• 2 + x
• 2x
• x + 2

• x * 2

Write the phrase as an expression:

25 more than 50

HINT: there are two correct answers

• 50 + 25

• 50 - 25
• 25 - 50
• 25 + 50

Use the Distributive Property to simplify the expression.

4 (x + 8)

• 4x * 8
• 4x - 8
• 4x + 8
• 4x + 32

Use the Distributive Property to simplify the expression.

12 (y - 5)

• 12y - 5
• 12y + 60
• 12y - 60
• 12y - 55

Simplify the expression:

r + 3r + 4r

• 8r
• 12r
• 7r
• r^3

Simplify the expression:

3 (2 + 5c) + 11

• 15c + 17

• 6 + 5c + 11
• 5c + 14

• 3 + 10c + 11

Factor the expression using the GCF.

18 + 24

• 6(3 + 4)
• 12(1 + 2)
• 9(2 + 3)
• 2(9 + 12)

Factor the expression using the GCF.

32x - 40y

• 2(16x - 20y)
• 8(4x - 5y)
• 4(8x - 10y)
• 16(2x - 2.5y)
