Answer:
The Geometric Mean of 4 and 12 is 6.9
Step-by-step explanation:
Given Numbers are 4 and 12
To find : Geometric mean of the given No.
The Geometric Mean is a type of average where we multiply the nos. together and then take a square root (for two nos), cube root (for three nos) etc.
Formula for Geometric Mean is given by,
![Geometric\,Mean\,of\,x_1\,,\,x_2\,,\,x_3..x_n=\sqrt[n]{x_1\times x_2\times x_3\times\,...\,\times x_n}](https://tex.z-dn.net/?f=Geometric%5C%2CMean%5C%2Cof%5C%2Cx_1%5C%2C%2C%5C%2Cx_2%5C%2C%2C%5C%2Cx_3..x_n%3D%5Csqrt%5Bn%5D%7Bx_1%5Ctimes%20x_2%5Ctimes%20x_3%5Ctimes%5C%2C...%5C%2C%5Ctimes%20x_n%7D)
⇒ Geometric Mean of 4 and 12 = 
= 
= 
= 6.92820323028
= 6.9
Therefore, The Geometric Mean of 4 and 12 is 6.9

Step-by-step explanation:
Answer:
5(9b + 8)
Step-by-step explanation:
Rewrite 45 as 5 * 9
Rewrite 40 as 5 * 8
= 5 * 9b + 5 * 8
Factor out common term 5
=5 (9b + 8)
B is less than or equal to -11
