Factor the expression:
9x(x^2 - 1) - 3(x^2 - 1)

Need on this geometry question. explain how you did it.

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Astudent has created the give circuit diagram. it consists of a battery, a resistor, and a light bulb. in one minute, 1.2c of charge flows through the resistor. how much charge flows through the light bulb in one minute?
