Answer:
4n^3 -10n^2 +16n -10
Step-by-step explanation:
Use the distributive property to eliminate parentheses, then combine like terms.
= 2n(2n^2 -3n +5) -2(2n^2 -3n +5)
= 4n^3 -6n^2 +10n -4n^2 +6n -10
= 4n^3 +n^2(-6-4) +n(10+6) -10
= 4n^3 -10n^2 +16n -10
2(3y-3) simplified is 6y-6
Its A, because a filled in circles means equal to and the arrow is going to the negatives because its less than 15.
3x+1=43
3x=42 (take one from each side)
x=14 (divide each side by 3)
the answer is 14
