Answer:
Work out the Mean (the simple average of the numbers)
Then for each number: subtract the Mean and square the result.
Then work out the mean of those squared differences.
Take the square root of that and we are done!

Step-by-step explanation:
Answer:
y = 3x - 6
Step-by-step explanation:
slope intercept form is: y = mx + b
m is your slope, so figure it out by doing rise/run
you rise 3, over one which is 3/1, but simplifies to 3
b is your y-intercept, find it by seeing where the line crosses the y-axis, which is -6
therefore, your answer is: y = 3x - 6
Answer:
Let the breadth is x, then the length is 3x.
<u>The area is:</u>
<u>The breadth is decreased by 2 m: </u>
<u>The length is increased by 4m: </u>
<u>The area is now:</u>
- (x - 2)(3x + 4) = 3x² - 1/3(3x²)
- 3x² + 4x - 6x - 8 = 2x²
- x² - 2x - 8 = 0
- x² - 2x + 1 = 9
- (x - 1)² = 3²
- x - 1 = 3
- x = 4
The breadth was 4 m and the length 12 m
