1. 4(4k+2)-8(k-1) ≤ 3(2k+2)-1
Type the solution set in interval notation. Thanks to whoever can help! :)
2. Give the simplified form written in descending powers fo the variable, the degree and the type of the following polynomial
9m^6-8m^2+6m^9-5m^4
How would you simplify this? And what is the degree of the polynomial?

4(4k+2)-8(k-1) ≤ 3(2k+2)-1
16.k + 8 - 8.k + 8 ≤ 6.k + 6 - 1
2.k ≤ - 11
9m^6-8m^2+6m^9-5m^4 =
6.m^9 + 9.m^6 - 5.m^4 - 8.m^2
The degree of this polynomial is 9
