Simplify:
-3(x - 4) + 3(a - 6)

• -3x + 3a - 6
• -3x + 3a - 30
• -9ab - 6
• -9ab - 30

Simplify:
2x (-2x - 3)

• -4x - 3
• x² - 3
• -4x² - 6x
• -4x - 6

Simplify the Expression:

7x² - 3a +20 - 4x² + 2a

• 11x² - a + 20

• 3x² - a + 20

• 2a + 20

• 3x² - a

(x +2)(x + 3)

• x² + 5x + 6
• x² + x + 6

A fitness club opens with 80 members. Each month the membership increases by 15 members. Which equation represents the relationship between the number of months the club has been opened, x, and the total fitness club membership, y?

• y=15x
• y=15x+80
• y=x+15
• y=80x+15

2. Cheryl gets paid $8 per hour for her job at the record store.  She made a total of $96 last week.  Which equation models this situation?

• 96h = 8
• h/96 = 8
• 8h = 96
• h/8 = 96

Solve: 5x + 15 = 10x - 40

• x = 10

• x = -10

• x = 11

• x = -11
