Can anyone help me with this

B: 10n⁵ + 11n³ - 6

Step-by-step explanation:

(-3 + 3n⁵ + 6n³) + (7n⁵ + 5n³ - 3)

To add the variables, you can only combine the variables with the same degree.

Because you are adding the polynomials, you can remove the parentheses.

-3 + 3n⁵ + 6n³ + 7n⁵ + 5n³ - 3

Now you can combine the variables that are raised to the same degree.

(-3 - 3) + (3n⁵ + 7n⁵) + (6n³ + 5n³)

Now simplify within the parentheses.

(-6) + (10n⁵) + (11n³)

Now reorder the variables from greatest to least degree.

10n⁵ + 11n³ - 6

step-by-step explanation:

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
