90% of Mr. Mitchell's class made a passing grade last 9-weeks. If 135 students made a passing grade in Mr. Mitchell's class, how many students
does he teach?
HELP MAYBE ?

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.
