The dartboard is made up of three concentric circles with radii 1, 3, and 5. Assuming that a dart thrown will land randomly on the dartboard, what is the
probability that it lands in the green region? (5 points)

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.
