Simplifying Expressions Combining Like Terms and Distributive Property

Simplify the Expression: 3(x - y + 5)

• 3x - 3y + 8

• 3xy + 15

• 3x + 3y + 8

• 3x - 3y + 15

Simplify the Expression: -1(2x + 3) - x

• -x + 3

• 3x + 3

• 4x + (-2)

• -3x - 3

Simplify the expression.
(4a³ - 8a - 4a²) + (7a³ - 7 - 6a)

• 11a³ - 4a² - 14a - 7 

• 5a³ - 4a² - 14a - 7 

• 5a³ - 4a² - 20a - 7 

• 5a³ - 9a² - 20a - 7

These have the the same variable and can, therefore, be combined...
