Answer:
5![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Step-by-step explanation:
The geometric mean of 2 numbers a and b is
![\sqrt{ab}](https://tex.z-dn.net/?f=%5Csqrt%7Bab%7D)
Hence
The geometric mean of 5 and 10 is
![\sqrt{5(10)}](https://tex.z-dn.net/?f=%5Csqrt%7B5%2810%29%7D)
= ![\sqrt{50}](https://tex.z-dn.net/?f=%5Csqrt%7B50%7D)

= 5![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Answer:
4140
Step-by-step explanation:
360/25 = 14.4
180 - 14.4 = 165.6
165.6 x 25 = 4140
Answer:
144
Step-by-step explanation:
exponents first: ![4^{3} = 64](https://tex.z-dn.net/?f=4%5E%7B3%7D%20%20%3D%2064)
then division: 100/5 = 20
now we have: 20 x 4 + 64
then multiply: 20 x 4 = 80
then add: 80 + 64 = 144
Answer:
g=-1
Step-by-step explanation:
3(g+4)=9
Divide both sides by 3.
g+4= 9/3
Divide 9 by 3 to get 3.
g+4=3
Subtract 4 from both sides.
g=3−4
Subtract 4 from 3 to get −1.
g=−1
