Answer:

x = 4/9

Step-by-step explanation:

Solve for x

7/4 x -2  = -5x +1

Add 5x to each side

7/4 x -2+5x  = -5x +1+5x

7/4 x  + 5x -2  = 1

Get a common denominator for the x terms

7/4x  +20/4x -2 = 1

Add 2 to each side

27/4 x -2+2 = 1+2

27/4 x = 3

Multiply each side by 4

27/4 x *4 = 3*4

27x = 12

Divide each side by 27

27x/27 = 12/27

x = 12/27

Simplify

x = 4/9

Answer:

A quadrilateral become square if all the sides joining the co-ordinate of quadrilateral is equal

Step-by-step explanation:

Here the given co-ordinate of quadrilateral are

G (3, -1)                  O(1, -6)

L(-4, -4)                  F(-2, 1)

Line GF = \sqrt{(3+2)^2+(-1-1)^2}

       GF = \sqrt{29}

Similarly for line OG, OL, FL

      OG = \sqrt{(1-3)^2 +(-6+1)^2

      OG = \sqrt{29}

     

      OL = \sqrt{(-4-1)^2+(-6+4)^2}

      OL = \sqrt{29}

And

      FL = \sqrt{(-4+2)^} +(-4+1)^2

      FL = \sqrt{29}

all the sides of quadrilateral GF,  OG, OL, FL all equal to \sqrt{29}

As all the sides are equal so quadrilateral become square      Answer
