Which polynomial, when added to the polynomial 5x^2-3x-9 is equivalent to: 18

- 5x² + 3x + 27

Step-by-step explanation:

To find the polynomial subtract 5x² - 3x - 9 from 18, that is

18 - (5x² - 3x - 9) ← distribute parenthesis by - 1

= 18 - 5x² + 3x + 9

= - 5x² + 3x + 27 ← required polynomial

it should be a and d. lmk if i'm wrong xd
