Tiffany bought a used car that had 25,037 miles recorded on the odometer. If Tiffany drives 1,044 miles per month, which of the following functions represents the number of miles, M(x), that will be recorded on the odometer after x months?

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.
