Question

In the equation above c is a constantly . if n =5 , what is the value of c ?

Answer 1

Answer:

D

Step-by-step explanation:

5 - Sqrt 11 + 5 = 1

5 - Sqrt 16 = 1

5 - 4 = 1

Answer 2

Answer:

D

Step-by-step explanation:

Given

5 - $\sqrt{c+5}$ = 1 ( subtract 5 from both sides )

- $\sqrt{c+5}$ = - 4 ( multiply both sides by - 1 )

$\sqrt{c+5}$ = 4 ( square both sides )

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

c = 11
