Answer:
3x^11+9x^7+5x^3-x+4
Step-by-step explanation:
A polynomial written in decreasing order is a polynomial that starts with terms with the highest degree and ends with terms to the lowest degree.
First find the decreasing order of the answer:
5x^3-x+9x^7+4+3x^11
The answer should be this, but I couldn't find a match for it in the answer box.
