A pole that is 3.1 m tall casts a shadow that is 1.65 m long. At the same time, a nearby building casts a shadow that is 44.75 m long. How tall is the building? Round your answer to the nearest meter.

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.
