The standard deviation is the square root of the variance...so that means the variance is the standard deviation squared.
2.3^2 = 5.29 <===
X = 11
angle LKM = angle KLM = angle LMK because it is an equilateral triangle
180/3 = 60
60=3x-27
60-27=3x
33=3x
x=11
There were 72 more maple trees before the bug problem then after because there was 108 maple trees before the bug problem and 36 maple trees after the bug problem
You could use so many for example 4, 10, 57, 5729, any number above 4 would work since that plus 8 would be greater than 11
The perimeter of a shape is the sum of the lengths of its sides.
So, to find the perimeter of this quadrilateral, all we have to do is add the side lengths and simplify.
(x² - 6) + (2x + 5) + (x² - 3x) + (4x² + 2x)
x² + x² + 4x² + (-3x) + 2x + 2x + (-6) + 5
6x² + (-3x) + 2x + 2x + (-6) + 5
6x² + x + (-6) + 5
6x² + x + (-1)
6x² + x - 1
So, the perimeter of the quadrilateral is the quantity (6x² + x - 1).
Hope this helps!
