Please help
I’m doing a multiple choice test

The answer is 4pi/3,

10pi/3-6pi/3= 4pi/3

Or

10pi/3-2pi= 4pi/3

6pi/3 is another way to say 2pi in the problem since the denominator is 3

21

step-by-step explanation:

21-4

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.
