Which expression has the same value as the one below?

8 + left-bracket 4 + (negative 9) right-bracket
12 + (negative 9)
Negative 12 + 9
Negative 4 + (negative 9)
4 + (negative 9)

8 + [4+(-9)] So the first one-> 12 + (-9)

I’m guessing that the answer is c, but i’m not sure which grid is being talked about. since 5x5= 25 and 3x3= 9 (which there are no answers for). a is not right because while the ratio is the same, 6/25= 0.24 which is equal to 24% not 30%.
