Answer:
Given equation: ![x^2-8x =39](https://tex.z-dn.net/?f=x%5E2-8x%20%3D39)
when we complete the square , we take half of the value of 8 , then square it, and added to the left sides, we get;
![x^2-8x+4^2 = 39 +4^2](https://tex.z-dn.net/?f=x%5E2-8x%2B4%5E2%20%3D%2039%20%2B4%5E2)
∵8 is the value ![(\frac{8}{2})^2](https://tex.z-dn.net/?f=%28%5Cfrac%7B8%7D%7B2%7D%29%5E2)
Notice that, we add this both sides so that it maintains the equality.
then;
![x^2-8x+4^2 = 39 +4^2](https://tex.z-dn.net/?f=x%5E2-8x%2B4%5E2%20%3D%2039%20%2B4%5E2)

Simplify:
![(x-4)^2 =55](https://tex.z-dn.net/?f=%28x-4%29%5E2%20%3D55)
The number must be added to complete the square is, ![4^2 = 16](https://tex.z-dn.net/?f=4%5E2%20%3D%2016)
Answer:
$163
Step-by-step explanation:
Bob worked 26 hours and earn $7 per hour. Multiply 26 with 7:
26 x 7 = 182
Bob made a total of $182 last month.
Bob then spent $19. Subtract 19 from the total earned:
182 - 19 = 163
Bob has $163 left.
