Answer:
D
Step-by-step explanation:
(3x³ - 10x² + 13x)  -  (5x³ + 4x² - 9x)
 3x³ - 10x² + 13x  - 5x³ - 4x² + 9x  Change all terms after the subtraction sign to 
                                                       the opposite sign (definition of Subtraction)
(3x³ - 5x³) + (-10x² - 4x²) + (13x + 9x)    Group like terms together
-2x³ - 14x² + 22x
