Step-by-step explanation:
2x(3x2 + 8x – 4) – 3(2x2 + x – 5)
Distribute
6x^3 + 16x^2-8x -6x^2 -3x+15
Combine like terms
6x^3 + 16x^2 -6x^2 -3x-8x+15
6x^3 +10x^2 -11x +15
Standard form is from highest to lowest power
6x^3 +10x^2 -11x +15

Answer:
- 1 1/3=k
Step-by-step explanation:
8 / 5 = -1 1/5k
To isolate the K we need to divide each side by -1 1/5
8/5 / -1 1/5 =k
now we can use kcf to divide
8/5 x -5/6 =k
multiply straight across
-40/30 =k
simplify
-4/3 = -1 1/3 =k
