Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-6,-4), B(-4,-4),C(-4,-2), and D(-6,-2). What is the perimeter of rectangle ABCD?

Step-by-step explanation:

In order to figure out what the perimeter of the rectangle you got to make a graph

As you can see I've graphed my rectangle using desmos which is a useful free app where you can make graphs

Then I simply count all the sides and you get the perimeter!

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)
