Answer:
x > -7/12. This is the answer to this question.
The answer would be b or number 12
(3x^3 + 4x²) + (3x^3 – 4x^2 – 9x) =
We have to combine like terms, terms that have x raised to the same power:
First, eliminate the parenthesis:
3x^3 + 4x² + 3x^3 – 4x^2 – 9x =
We have 2 terms raised to the second power (4x^2 and -4 x^2) simply add and subtract.
3x^3+3x^3+4x^2-4x^2-9x
6x^3-9x
1/2x6 does not belong because it is not a mixed number equation.
5. since .6 is greater than 5, we round up.
