Slade Castaneda · Answer 1

The answer is:

B. (5x2 - 2x + 10) - (3x2 + 3x) = 2x2 - 5x + 10)

Gabriel Mitchell · Answer 2

B

Step-by-step explanation:

subtract the volume of the small box from the large box, that is

5x² - 2x + 10 - (3x² + 3x)

= 5x² - 2x + 10 - 3x² - 3x (collect like terms)

= 2x² - 5x + 10 → B
