➷ You know when you multiplied the top and bottom by root 13?
Root 13 multiplied by root 13 would be 13
You forgot to put that in
If you put that in, the 13 on the top and the 13 on the bottom will cancel out, leaving root 13.

Answers:
- Original = 1 ----> Enlarged = 6
- Original = 7 ----> Enlarged = 42
- Original = 2.5 ----> Enlarged = 15
- Original = 6 ----> Enlarged = 30
It looks like you have the correct order. To get those answers above, we simply multiply the original length by the scale factor 6.
Example: 7*6 = 42
Answer:
![\frac{dy}{dx}=\frac{1}{2(x-4)}](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D%5Cfrac%7B1%7D%7B2%28x-4%29%7D)
Step-by-step explanation:
We are given that a function
We have to find the derivative of the function
![y=\frac{1}{2}ln(x-4)](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7Dln%28x-4%29)
By using ![lna^b=blna](https://tex.z-dn.net/?f=lna%5Eb%3Dblna)
Differentiate w.r.t x
![\frac{dy}{dx}=\frac{1}{2}\times \frac{1}{x-4}](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5Cfrac%7B1%7D%7Bx-4%7D)
By using formula
![\frac{d(lnx)}{dx}=\frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%28lnx%29%7D%7Bdx%7D%3D%5Cfrac%7B1%7D%7Bx%7D)
![\frac{dy}{dx}=\frac{1}{2(x-4)}](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D%5Cfrac%7B1%7D%7B2%28x-4%29%7D)
Hence, the derivative of function
![\frac{dy}{dx}=\frac{1}{2(x-4)}](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D%5Cfrac%7B1%7D%7B2%28x-4%29%7D)
The answer, is CD. The 3rd one
