5 - Sqrt 16 = 1

5 - 4 = 1

Answer:

D

Step-by-step explanation:

Given

5 - [tex]\sqrt{c+5}[/tex] = 1 ( subtract 5 from both sides )

- [tex]\sqrt{c+5}[/tex] = - 4 ( multiply both sides by - 1 )

[tex]\sqrt{c+5}[/tex] = 4 ( square both sides )

c + 5 = 4² = 16 ( subtract 5 from both sides )

c = 11
