BD = AC/2
4x+2 = (5x+13)/2
2(4x+2) = 5x+13
8x + 4 = 5x+13
8x - 5x = 13 -4
3x = 9
x = 3
Its already written as a decimal but it can be 8 1/2
I'm assuming the given log equation is 
If so, then the exponential form is 
This is because the general form 
transforms into 
For both equations, the 'b' is the base.
Answer:
x = 2
Step-by-step explanation:
OK so lets do it together.
2x = -2x + 8
Subtract 8 from both sides
2x - 8 = -2x
Add 2x to both sides
4x - 8 = 0
Add 8 to both sides
4x = 8
Divide each side by 4
x = 2
Check:
4 = -4 + 8
4 = 4
correct

The standard deviation is the square root of the variance...so that means the variance is the standard deviation squared.
