I would help you but I can't see it maybe zoom in a little closer.
How many jumps is it from the decimal point to the position to the right of the 6
The answer to that is 3 jumps. Since the move of the decimal made the number larger than it really is, it will take a negative value to put it back where it belongs.
So A) is the correct answer. It is in scientific notation and if you move the decimal back 3 place you get the number you stared with.
3 terms
when you combine like terms you are left with 10x + y + 8 which is 3 terms.
