This is the picture I am not very good at proofs but hopefully someone can solve it.
Answer:
3n(7n^3-5n+5n)
21n^3 -15n +15n
21n^4
Step-by-step explanation:
3n(7n^3-5n+5n)
21n^3 -15n +15n
21n^4
Answer:
B
Step-by-step explanation:
sum of angles in a triangle is 180
6n +1 +108+9n-4=180
15n = 180 -105
15n = 75
n= 75/15 = 5
