I think your missing one which is G
I can’t see your choices, but this equation can be simplified to 5y + 5.
If you add the choices as a comment, I’m happy to help more.
Answer:
C = 24
Step-by-step explanation:
(x - 6)² - 12 = x² - 12x + c
(x - 6) (x - 6) -12 = x² - 12x + c
x(x - 6) - 6(x - 6) - 12 = x² - 12x + c
x² - 6x -6x + 36 - 12 = x² - 12x + c
x² - 12x +36 - 12 = x² - 12x + c
x² - 12x + 24 = x² - 12x + c
24 = c
