Katie practice the flute for 45 minutes then she ate a snack for 15 minutes next she watched television for for 30 minutes until 6 o'clock p. m. at what time did katie start playing the flute

Well let's see, how about we subtract 6 P.M from 30 minutes and that is 5:30 P.M then we subtract 5:30 by 15 minutes, and we get 5:15 P.M then we subtract 5:15 P.m by 45 minutes and we get 4:30 P.M

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.
