Answer:
![\huge\boxed{\sf x = 7}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5Csf%20x%20%3D%207%7D)
Step-by-step explanation:
<u><em>According to the given statement</em></u>
HJ = HK + KJ
Given that HJ = 25 , HK = x - 5 and KJ = 5x-12
![\sf 25 = x-5+5x-12](https://tex.z-dn.net/?f=%5Csf%2025%20%3D%20x-5%2B5x-12)
Adding like terms
![\sf 25 = 6x-17\\Adding \ 17\ to\ both\ sides\\25 + 17 = 6x\\42 = 6x\\Dividing \ both \ sides \ by \ 6\\7 = x\\OR\\x = 7](https://tex.z-dn.net/?f=%5Csf%2025%20%3D%206x-17%5C%5CAdding%20%5C%2017%5C%20to%5C%20both%5C%20sides%5C%5C25%20%2B%2017%20%3D%206x%5C%5C42%20%3D%206x%5C%5CDividing%20%5C%20both%20%5C%20sides%20%5C%20by%20%5C%206%5C%5C7%20%3D%20x%5C%5COR%5C%5Cx%20%3D%207)

Since the curtains are going up in .25. We need to add .25 to 1.5.
1.5 + .25 = 1.75
Answer:
Find the surface area of her notebook.
30 + 30 + 20 + 20 = 100
Now find the surface area of the square stickers.
2 + 2 + 2 + 2 = 8
So this is the surface area of one square, now multiply it by 8.
8 * 7 = 56
This is the surface area of all the stickers, now subtract it to the surface area of the notebook:
100 - 56 = 44
So 44 centimeters of the notebook cover will still be showing.
