What is the distance around a triangle that has side measuring 2 1/8 feet, 3 1/2, and 2 1/2 feet? ? a: 7 1/8 feet b: 7 9/24 feet c: 8 feet d 8 1/8 feet show work plz

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)
