Barry's deck of cards contains 40 blue cards and 70 red cards. maxs deck of cards contains the same number of blue cards, but the ratio of blue cards to red cards to red cards is 8: 9.how many total cards does max's deck of cards contain?

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.
