There are two sizes of milk to choose from at the grocery store. A 3-quart carton costs $2.78, while a 4-quart carton costs $3.87. Which is the better buy and why?

Same length is comparing because it’s saying its the same and not different

What’s your question.

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.
