The scale below was taken from a housing blueprint. Use the information below to select the proportion that represents this situation if the length of the room on the actual house is 20
feet long.

.25 20
—— = ——
2 X

.25 2
=
20 X

.25 X
=
2 20

1. 2
--- = ---
4 20

Pls help meee

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)
