The histogram shows the distributions of prices for packs of adult socks and packs of kid socks at a store. which measure of center is the best to use to compare the prices of kid socks and adult socks? range mean median standard deviation

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.
