Answer:
10c^3 -30c^2 + 10c -30
Step-by-step explanation:
2c(5c^2+5) - 6(5c^2+5)
= 10c^3 + 10c - 30c^2 - 30
= 10c^3 -30c^2 + 10c -30
3x +3(x-10) = 360
3x +3x-30 =360
6x-30 =360
6x=390
X = 390/6 = 65
65-10 =55

Answer: 266
Step-by-step explanation: This is a ratio problem. If there are 14 chocolates with nuts out of every 32 chocolates, you can use this as a ratio and set it up as a proportion.

(2) Solve for n: 8,512 = 32n; n = 266
