Answer:
The solution of square root 2x+4 =16 is x = 126
Step-by-step explanation:
It is given that
square root (2x+4 )=16
√(2x+4 )=16 ----- (1)
Squaring both side of equation we get
[√(2x+4 )]^2=16^2
2x + 4 = 256
2x = 256 - 4
2x = 252
x = 252/2 = 126
Therefore the solution of square root 2x+4 =16 is x = 126
Answer:
[tex]x=126[/tex]
Step-by-step explanation:
[tex]\sqrt{2x+4} =16[/tex]
To find solution , we need to solve for x
In order to get x alone, eliminate the square root
To remove square root , take square on both sides
[tex]\sqrt{2x+4} =16[/tex]
[tex](\sqrt{2x+4})^2=16^2[/tex]
[tex]2x+4= 16 \cdot 16[/tex]
[tex]2x+4= 256[/tex]
Subtract 4 on both sides
[tex]2x= 252[/tex]
Divide both sides by 2
[tex]x=126[/tex]
