Answer:
![n = 3](https://tex.z-dn.net/?f=n%20%3D%203)
![XY = 39](https://tex.z-dn.net/?f=XY%20%3D%2039)
![XZ = 39](https://tex.z-dn.net/?f=XZ%20%3D%2039)
Step-by-step explanation:
Given
![XY = 9n + 12](https://tex.z-dn.net/?f=XY%20%3D%209n%20%2B%2012)
![XZ = 15n - 6](https://tex.z-dn.net/?f=XZ%20%3D%2015n%20-%206)
![](https://tex.z-dn.net/?f=%3CXYZ%20%3D%20%3CYZX)
Solving (a): n
To solve for n;
We make use of
![XY = XZ](https://tex.z-dn.net/?f=XY%20%3D%20XZ)
Substitute values for XY and XZ
![9n + 12 = 15n - 6](https://tex.z-dn.net/?f=9n%20%2B%2012%20%3D%2015n%20-%206)
![9n - 15n = -12 - 6](https://tex.z-dn.net/?f=9n%20-%2015n%20%3D%20-12%20-%206)
![-6n = -18](https://tex.z-dn.net/?f=-6n%20%3D%20-18)
Divide through by -6
![n = 3](https://tex.z-dn.net/?f=n%20%3D%203)
Solving (b) XY
![XY = 9n + 12](https://tex.z-dn.net/?f=XY%20%3D%209n%20%2B%2012)
Substitute 3 for n
![XY = 9 * 3 + 12](https://tex.z-dn.net/?f=XY%20%3D%209%20%2A%203%20%2B%2012)
![XY = 27 + 12](https://tex.z-dn.net/?f=XY%20%3D%2027%20%2B%2012)
![XY = 39](https://tex.z-dn.net/?f=XY%20%3D%2039)
Solving (c): XZ
![XZ = XY](https://tex.z-dn.net/?f=XZ%20%3D%20XY)
![XZ = 39](https://tex.z-dn.net/?f=XZ%20%3D%2039)

<u>Step-by-step explanation:</u>
Given to us is , 5 ( x + 12 ) and we need to find which is its equivalent in the given options .
So,
![\bf = 5 ( x + 12 ) \\\\=\bf 5x + 5\times 12 \\\\=\boxed{\red{\bf 5x + 60 }}](https://tex.z-dn.net/?f=%5Cbf%20%3D%205%20%28%20x%20%2B%2012%20%29%20%5C%5C%5C%5C%3D%5Cbf%205x%20%2B%205%5Ctimes%2012%20%5C%5C%5C%5C%3D%5Cboxed%7B%5Cred%7B%5Cbf%205x%20%2B%2060%20%7D%7D)
