Using the Associative Property, how would we simplify this problem?

6 + (5 + x)

• 6 + 5x

• (x + 5) + 6

• (6 +5) + x

• (6 + 5 + x)

Simplify the expression using the Distributive Property:  4( x - 6)

• x- 24
• 4x - 24
• 4x + 6
• 4x + 24

Simplify the expression.
6q + 2 + 3q+ 5

• 6q + 3q + 2 + 5
• 18q + 10
• 2(3q + q) + 7 
• 9q + 7

Simplify the expression.
4r + 3(r - 2)

• 7r - 6
• 5r + -6
• r - 6
