Respuesta :
- 10 + √(x + 8) = - 4
Add 10 to both sides to get:
√(x + 8) = 6
Square both sides to get our binomial out of the square root:
x + 8 = 6²
x + 8 = 36
Subtract 8 to both sides to get:
x = 28
Add 10 to both sides to get:
√(x + 8) = 6
Square both sides to get our binomial out of the square root:
x + 8 = 6²
x + 8 = 36
Subtract 8 to both sides to get:
x = 28
Answer:
[tex]x=28[/tex]
Step-by-step explanation:
[tex]-10+\sqrt{x+8}=-4[/tex]
⭆ Add 10 to both sides:-
[tex]-10+\sqrt{x+8}+10=-4+10[/tex]
[tex]\sqrt{x+8}=6[/tex]
⭆ Square both sides:-
[tex]x+8=36[/tex]
⭆ Subtract 8 from both sides:-
[tex]x+8-8=36-8[/tex]
[tex]x=28[/tex]
