Answer:
Step-by-step explanation:
Factor
x^2-6x+8<0
(x-2)(x-4)<0
For this to be less than zero the factors must have opposite signs.
x>2 and x<4
2<x<4
So x is all real numbers between 2 and 4 or in interval notation
x=(2,4)
The answer to you promovem would be 2,291.9 miles away
I think the discriminant would be -24
The 2 triangles in the big triangle are similar so we can write
3x / 3x - 2 = 5x / 3x
9x^2 = 15x^2 - 10x
6x^2 - 10x = 0
x(6x - 10) = 0
x= 0 or 5/3
The formula of an area of parallelogram:
We have
and 
Substitute:
<em>divide both sides by 6.3</em>
