Answer:
6 , 9
Step-by-step explanation:
Step 4-5 is where Andrew made an error. Since 9.8 is positive, -11.8 + 9.8 = -2. He subtracted 9.8 from 11.8 instead of adding it.

Answer:
(y+4) /2
Step-by-step explanation:
(y²-16)/(2y+6) × (y+3)/(y-4) =
(y+4)(y-4) / 2(y+3) × (y+3)/(y-4)
=> eliminate all (y-4) and (y+3)
so, we get :
(y+4)/2
The answer would be letter b because you would take the -2 and divide it by the half then take negative four subtract 6
