Apicture is photocopied by using a scale of 2. each side of the photocopy of the picture is

each side of the photocopy is enlarged by a factor of 2

Step-by-step explanation:

scaling by any factor literally means to multiply each side of the shape with that factor.

so for example: for a shape with side length = ,

scaling of that shape of factor means that length of the sides are

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)
