The assembly machine in your plant can produce 36,200 parts in 9 hours. how many parts can it produce in 18 hours?

Multiply the total by 2. 36,200 * 2 = 72,400

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.
