Answer:

9. 12u² + 15u - 5ut - 9 is your answer

10. 7a³ - 12ab² - 5 is your answer

Step-by-step explanation:

Combine like terms (terms with the same amount of variables):

9. 4u² + 8u² + 15u - 5ut - 9

(4u² + 8u²) + 15u - 5ut - 9

12u² + 15u - 5ut - 9

12u² + 15u - 5ut - 9 is your answer

10. 3a³ - 11ab² + 4a³ - ab² - 5

(3a³ + 4a³) (- 11ab² - ab²) - 5

7a³ - 12ab² - 5

7a³ - 12ab² - 5 is your answer
