x = 10.0

Step-by-step explanation:

Using the geometric mean formula:

       x                projection

 =  

entire base              x

Here, the projection is 5 and the entire base is (20 + 5). So:

       x                5

 =  

      25              x

Cross multiply:

x² = 25 (5)

x² = 100

√x² = √100

x = 10

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
