Answer:
28 - 4x
Step-by-step explanation:
![18 -2 [x + (x - 5)] \\ = 18 - 2 [x + x - 5] \\ = 18 - 2 [2x - 5] \\ = 18 -4x + 10 \\ = 28 - 4x \\](https://tex.z-dn.net/?f=18%20-2%20%5Bx%20%2B%20%28x%20-%205%29%5D%20%20%5C%5C%20%20%3D%2018%20-%202%20%5Bx%20%2B%20x%20-%205%5D%20%20%5C%5C%20%20%3D%2018%20-%202%20%5B2x%20-%205%5D%20%5C%5C%20%20%3D%2018%20-4x%20%20%2B%2010%20%5C%5C%20%20%3D%2028%20-%204x%20%5C%5C%20)
399,499.
Since we are rounding to the nearest thousand, we are going to be focusing on mainly 39(9,499). The rule I learned is, "5 or above, give it a shove". Since it isn't 500 or above, we have to round it down to 9,000.
The total is 399,000.

Answer:
Step-by-step explanation:
Solution:
AM =( X_1 + X_2 )/2
=( 18 + 2 )/2
=20/2
=10
Find Geometric mean for data 18,2
Solution:
GM =sqrt( X_1 × X_2 )
=sqrt( 18 × 2 )
=sqrt(36)
=6
