An artist has been commissioned to make a stained glass window in the shape of a regular octagon. The octagon must fit inside a 14 in square space. Determine the length of each side of the octagon. Round your answer to the nearest hundredth of an inch

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.

The final answer is a
