Answer:
![x=-2](https://tex.z-dn.net/?f=x%3D-2)
Step-by-step explanation:
The given expression is
![\sqrt{x+3}+4=5](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B3%7D%2B4%3D5)
We group the constant terms on the right hand side to obtain;
![\sqrt{x+3}=5-4](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B3%7D%3D5-4)
![\Rightarrow \sqrt{x+3}=1](https://tex.z-dn.net/?f=%5CRightarrow%20%5Csqrt%7Bx%2B3%7D%3D1)
We square both sides of the equation to remove the square root.
![\Rightarrow (\sqrt{x+3})^2=1^2](https://tex.z-dn.net/?f=%5CRightarrow%20%28%5Csqrt%7Bx%2B3%7D%29%5E2%3D1%5E2)
![x+3=1](https://tex.z-dn.net/?f=x%2B3%3D1)
This will simplify to;
![x=1-3](https://tex.z-dn.net/?f=x%3D1-3)
![x=-2](https://tex.z-dn.net/?f=x%3D-2)
Answer:
x=-4.22222
The 2 is repeating
Step-by-step explanation:
First you subtract 18 from both sides
9x=--38
Then divide both sides by 9
x=-4.22222
The 2 is repeating
Rational. Irrational are numbers that cannot be written as fractions. 8 can be written as a fraction. 8/1
I would personally take the number three and trow it out the window but that's not what we are talking about
