The mass of a moon rock is 3.5 kilograms. what is the mass of the moon rock in grams?

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.

Let us take option c(-3x + 6i)(x + 2i)-3x² - 6xi + 6xi + 12i²-3x² + 12i²we know that i² = -1-3x² - 12option c is the answer
