They are all correct

btw, to write powers in this format we use the ^ symbo

so x^2 means "x squared"

Jeremy is right

you guys are both right. #5 could be bothA or C.. just pay attention to the actual answer and not the letter because they are switched around.
5. is -2x^3-6x^2+9x

1) What is the degree of the monomial 3x^2y^3?
- The answer is 5; because 2+3+0 (0 is from 3 because it is a constant) added together equals 5.
2)What is the simplified form of 8b^3c^2 + 4b^3c^2?
- The answer is 12b^3c^2; because adding both equations together, results in that answer. It is simple addition.
3) What is the simplified form of (4j2 + 6) + (2j2 – 3)?
- The answer is 6j^2+3; NOT 6j^2+3, the difference is because 6 + -3 = 3; Marie is wrong about it being 6j^2+9. You're adding not subtracting.
4) What is the difference between the following polynomials?

(6x^3 – 2x^2 + 4)

– (2x^3 + 4x^2 – 5)
______________
- The answer is 4x^3-6x^2+9; It is not as hard as it looks, just subtracts it as you normally would.
5) f(x)= (3x3 – 4x2 + 6x) and g(x)= (5x3 + 2x2 – 3x). What is f(x) - g(x)?
- The answer is -2x^3-6x^2+9x; This is also another simple subtraction equation.
@Jeremy is correct!
