8x - 6 - 12x^2 + 9x
2(4x-3)-3x(3x-3)
=> (2-3x)(3x-3)
=> 3(x-1)(2-3x)
It would be D because the formula is: pi r^2
The answer is 20/3 first you set a variable x and 30x=200 divid both side by 30 and get the final answer
Uhhh I think it'd be C and... probably A or D. I'm not 100% sure, but if I was taking the test, that is what I would choose.
