Answer:
b
Step-by-step explanation:
first, group the terms with the same power together and it would become (-9n⁵-4n⁵)+(n³-9n³)+(11n+6n). then, combine the terms in each group together which would get -13n⁵-8n³+17n as the answer

If you solve it, the answer will be
C= 4.80
Seeing as its supposed to be a whole number, you will round up, so it will be 5
5.892700e+4 +
0.000000e+0 =
