Respuesta :
The inside of the radical must be greater than or equal to zero. When you plug in c=3, the answer is 5 >0. When c=-6, -4 <0. Therefore c=3 is true.
Answer:
c = 3
Step-by-step explanation:
the expression is [tex]\sqrt{c+2}[/tex]
Substitute, 3 for c, we get the value of expression is [tex]\sqrt{5}[/tex]
This value is possible because the square root is defined for positive values.
Substitute, - 6 for c, we get the value of expression is [tex]\sqrt{-5+2}[/tex]
This value is not possible because the square root of negative value sis not defined.
So, c = 3 is true for the given expression.
