Answer:
Ans.
X=3
Step-by-step explanation:
Ok, there are several ways to solve this, I chose the one that can be more visual friendly to you.
SInce the log are based 2, we are going to be using this base on both sides of the equation, so, let Y = (3X+7).
![Log_{2} (Y)=4](https://tex.z-dn.net/?f=Log_%7B2%7D%20%28Y%29%3D4)
![2^{Log_{2} (Y)} =2^{4}](https://tex.z-dn.net/?f=2%5E%7BLog_%7B2%7D%20%28Y%29%7D%20%3D2%5E%7B4%7D)
This means.
![Y=2^{4}](https://tex.z-dn.net/?f=Y%3D2%5E%7B4%7D)
Since Y = (3X+7)
![3X+7=2^{4}](https://tex.z-dn.net/?f=3X%2B7%3D2%5E%7B4%7D)
![3X=16-7](https://tex.z-dn.net/?f=3X%3D16-7)
![3X=9](https://tex.z-dn.net/?f=3X%3D9)
![X=\frac{9}{3}](https://tex.z-dn.net/?f=X%3D%5Cfrac%7B9%7D%7B3%7D)
Therefore X=3
Best of luck.
Answer:
13r
Step-by-step explanation:
Explanation:
This might not be how you are supposed to do it but,
We can see the two triangles are similar because AA similarity.
We know that the sides are proportional so we can make:
![\frac{x+2}{x}=\frac{4}{3x-1}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B2%7D%7Bx%7D%3D%5Cfrac%7B4%7D%7B3x-1%7D)
We get,
![3x^2+5x-2=4x\\3x^2+x-2\\(3x-2)(x+1)=0\\x=2/3, x=-1](https://tex.z-dn.net/?f=3x%5E2%2B5x-2%3D4x%5C%5C3x%5E2%2Bx-2%5C%5C%283x-2%29%28x%2B1%29%3D0%5C%5Cx%3D2%2F3%2C%20x%3D-1)
Because sides can't be negative, x = 2/3
