Answer:

u = 27

Step-by-step explanation:

sqrt(u+9) = 6

Square each side

(sqrt(u+9))^2 = 6^2

u+9 = 36

Subtract 9 from each side

u+9-9 = 36-9

u = 27

Answer:

U = 27, there is only one solution.

Step 1. Isolate the square root on the left hand side.

Step 2. Raise both sides to the second power.

(sqrt u+9)^2 = (6)^2

u+9=36.

Step 3. Solve the linear equation.

u -27 = 0

u =27

Hope this helps. :)
