6. Consider a quadrilateral and its diagonals. Which conjecture below would best describe a quadrilateral whose diagonals divide it into four isosceles triangles?

X> -2 is the simplified version.

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
