Sarah and kelvin are calculating the area of a circle with a radius of 52 cm. kelvin uses 3.14 for pi when calculating this area while sarah uses the pi button on her calculator. kelvin gets a solution of 8,490.56 cm2, and sarah gets a solution of 8,494.87 cm2.

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)

you can't solve x because it is 2 linear equation and you only have one equation
