Find the geometric mean between 12 and 20 find the answer in radical form or round to the nearest tenth if necessary ​

Geometric mean of two numbers is squre root of thir product.

Given numbers are 12,20

Geometric mean = √(12*20)

= √240

= 15.49

= 15.5

step-by-step explanation:

use a calculator!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
