Final Review

What problem represents the distributive property?

• 4x + 2x = 6x

• 4(3x - 6) = 12x - 24

• |a| = 5 therefore a = 5 or a = -5

• This is the first time I am hearing about the Distributive Property.

5(a + 6)

• 5a + 6
• a + 30
• 5a + 30
• 5a - 30

Factor:

5x²y - 10x³ + 15x⁴

• 5x²(y - 2x + 3x²)

• 5(x²y - 2x³ + 3x⁴)

• x2(5y - 2x + 15x²)

• Can't be factored

Simplify:
5x - 6x - 8x + 7 

• -9x + 7
• 10x + 7
• 9x + 7 
• 9x - 7
