Find f'(x) for f(x) = - 3x + 4) Do not simplify. x3 - x2 + 3x Select one: O A. 6(x3 - x2 + 3x)(3x + 4) - (3x + 4)2(3x2 - 2x + 3) (3x + 4)4 O B. 6(x3 -x2 + 3x)(3x + 4) - (3x + 4)²(3x2 - 2x + 3) (x3 - x2 + 3x)2 O C. (3x + 4)2(3x2 - 2x + 3) - 6(x3 -x2 + 3x)(3x + 4)

For this problem, assume the test had 6 true-false questions and 8 multiple-choice questions, and that each multiple-choice question had 5 choices. How many different answer sheets can be submitted?

What do you think is the best way of sorting out these type of questions. When I'm studying I somehow always mix up negative and positive values or get something off somehow. so that I get one part wrong which leads to getting another part wrong and so on. I understand the concept of elimination and subsition but I can't seem to carry it out very well.

Can i share my screen and show you a homework problem that I thought I did right but is wrong and I don't know what I've done wrong?
