Answer:
[tex]x=142[/tex]
Step-by-step explanation:
The given equation is:
[tex]\sqrt{x+2}-15=-3[/tex]
Adding 15 on both the sides, we get
[tex]\sqrt{x+2}-15+15=-3+15[/tex]
[tex]\sqrt{x+2}=12[/tex]
Squaring on both the sides of the equations, we have
[tex]x+2=144[/tex]
Subtracting 2 on both the sides, we get
[tex]x+2-2=144-2[/tex]
[tex]x=142[/tex]
Thus, the solution of the given equation is [tex]x=142[/tex].
Hence, option A is correct.
