Abarrel had 20 liters of water. water leaked out from the barrel at a constant rate. after 24 hours, 14 liters of water was left in the tank. how many liters of water leaked out per hour?

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.
