2 The Moon takes about 28 days to orbit the Earth, going a distance of about 2.413 x 105 kilometers. About how many kilometers does the Moon travel during one day of its orbit
around the Earth?
A 8.6 X 104 km
B 2.8 X 106 km
C 1.16 X 107 km
D 6.8 X 107 km

How many is in each case if there is 12 in each case it would be 40

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
