Plz help !! Me with it

Answer 1

Answer: b. 31

Explanation:

`4+√(x+5)=10\\\\√(x+5)=6\\\\(√(x+5))^2=(6)^2\\\\x+5=36\\\\x=31\\\\\\Check:\\4+√((31)+5)=10\\\\4+√(36)=10\\\\4+6=10\ \checkmark`

Answer 2

x=31

Explanation:

4+ sqrt (x+5) = 10

Subtract 4 from each side

4 -4+ sqrt (x+5) = 10-4

sqrt(x+5) = 6

Square each side

(sqrt(x+5))^2 = 6^2

x+5 = 36

Subtract 5 from each side

x+5-5 = 36-5

x = 31
