Answer:
x = -1
Step-by-step explanation:
Given
2x + 2 = 4x + 4 ( subtract 4x from both sides )
- 2x + 2 = 4 ( subtract 2 from both sides )
- 2x = 2 ( divide both sides by - 2 )
x = - 1

Answer:
n=30
Step-by-step explanation:
1/4(n+2)=8
1/4n+2/4=8
1/4n+2/4-2/4=8-2/4=7 2/4
1/4n=7 2/4
1/4n (4)=7 2/4 x (4)
n=29+2=30
Divide both sides by 174594
(3600000/174594)=ln(x/1.25)

![log_ex](https://tex.z-dn.net/?f=log_ex)
and
![log_ax=y](https://tex.z-dn.net/?f=log_ax%3Dy)
means
![a^y=x](https://tex.z-dn.net/?f=a%5Ey%3Dx)
so
(3600000/174594)=ln(x/1.25) means
![e^{ \frac{3600000}{174594} }=x/1.25](https://tex.z-dn.net/?f=e%5E%7B%20%5Cfrac%7B3600000%7D%7B174594%7D%20%7D%3Dx%2F1.25)
multily both sides by 1.25
![1.25e^{ \frac{3600000}{174594} }=x](https://tex.z-dn.net/?f=1.25e%5E%7B%20%5Cfrac%7B3600000%7D%7B174594%7D%20%7D%3Dx)
