Answer:
GCD(a,b) is multiple of d. It means d divides GCD(a,b).
Step-by-step explanation:
Let a and b are two unknown numbers.
If d divides a and d divides b, then a and b are multiple of d.
![a=d\cdot m=dm](https://tex.z-dn.net/?f=a%3Dd%5Ccdot%20m%3Ddm)
![b=d\cdot n=dn](https://tex.z-dn.net/?f=b%3Dd%5Ccdot%20n%3Ddn)
where, m and n are integers.
The greatest common divisor of a and b is
![GCD(a,b)=d\cdot m\cdot n](https://tex.z-dn.net/?f=GCD%28a%2Cb%29%3Dd%5Ccdot%20m%5Ccdot%20n)
![GCD(a,b)=d\cdot mn](https://tex.z-dn.net/?f=GCD%28a%2Cb%29%3Dd%5Ccdot%20mn)
GCD(a,b) is multiple of d. It means d divides GCD(a,b).
Hence proved.
Answer:
x = √y+18
Step-by-step explanation:
Given
![y = x^2-18](https://tex.z-dn.net/?f=y%20%3D%20x%5E2-18)
In order to solve the equation for x, we have to isolate x on one side of the equation
So,
![y+18 = x^2 -18 + 18\\y + 18 = x^2](https://tex.z-dn.net/?f=y%2B18%20%3D%20x%5E2%20-18%20%2B%2018%5C%5Cy%20%2B%2018%20%3D%20x%5E2)
We have to find the value for x, so taking square root on both sides
![\sqrt{x^2} = \sqrt{y+18}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2%7D%20%3D%20%5Csqrt%7By%2B18%7D)
Solving the squre root
x = ![x = \sqrt{y + 18}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7By%20%2B%2018%7D)
Hence,
x = √y+18 is the correct answer ..
