  9.9

Step-by-step explanation:

The applicable geometric mean rule tells you ...

  y = √(9(9+2)) = √99

  y ≈ 9.9

Additional comment

In this geometry, the right triangles are similar. Ratios of corresponding sides are equal.

  hypotenuse/long side = y/9 = (9+2)/y

  y^2 = (9)(11)

  y = √99 . . . . as above

The long leg is the geometric mean of the (adjacent) long segment and the full hypotenuse.

do you mean add both of the equations together

because if you do the answer is 10x-5
