Answer: 2
Step-by-step explanation:
So you distribute the -6 to the n and -1
Resulting info d(n)= 8-6n+6
Combine the 8 and 6. Getting 14
Add 6n in both sides getting
7n=14
Divide by 7
N=2
The only thing you can do with this expression is to factor a 5 out of the two terms: we have

Answer:
3.
Step-by-step explanation:
3(n + 4) = 21
3n + 12 = 21
3n = 21 - 12 = 9
n = 3.
Answer:
Step-by-step explanation:
1.

c+9=±8
either c=8-9=-1
c=-8-9=-17
so c=-1,-17
D
2.
8x^2-3=2
8x^2=5


so A
3.

so D
