Coz and amelia each make a tile design with 24 tiles. coz puts his in rows of 2.amelia puts hers in rows of 3.how many more tiles are in each of coz's rows than amelia's?

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.
