An architect is trying to find the perfect place to build a "A" shaped bridge over a river. The left side of the bridge begins at (-9,-4) and the right side of the bridge is at (9,-4).
The top of the "A" shaped bridge will be located at (0,2). Sea-level (ground level) is when y = -4.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

its adding 5.5 each time
