In the gift shop of history of the flight museum, elisa bought a kit to make a model of a jet airplane. the actual plane is 21 feet long with a wingspan of 17.5 ft. if the finished model will be 12 inches long, what will the wingspan be? a.) 14.4 inches b.) 30.6 inches c.) 5 inches d.) 10 inches

12 inches make a foot, therefore the scale model is 1/21 the size of the actual if you're using the information given above. so the wingspan should be 10

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.
