Josie's height = 5 ft 6 in. = 5 1/2 ft = 11/2 ft.
Josie's shadow = 6 ft.
Ratio of shadow to height = 6 / 11/2 = 12/11
So, It would be equal to ratio of building's shadow to building's height.
18/x = 12/11
x = 18*11 /12
x = 3*11 / 2
x = 16.5
In short, Your Answer would be 16.5 Feet
Hope this helps!

Answer:

Simplified it is 
Step-by-step explanation:
The x-intercepts of a parabola form the factors of the equation. Since the x -intercepts are (-2,0) and (4,0) then the factors are (x+2) and (x-4). Factors are pieces which multiply to make the equation.

This is the standard form of the parabola
. Since the y-intercept of the parabola is (0,4) then a number must also be multiplied to it

We find a by plugging in x=0 and y=4.

So the equation is
.
When simplified it is
