I think that the answer is -1/6. I got this by subtracting 3 on both sides according to the order of operations and got -1. Next, I divided 6 on both sides to undo the multiplication. Since you can't do 1 divided by 6, you can leave it as a fraction which is -1/6.
B because a negative squared is always a positive and it has to be a negativ number less than -3 is less than 9 and if it is greater than 3 than it would make it untrue.
