I can't see anything above question 7 clearly. Q7 and 8 needs that info at the top right?

For Q9, is that side on the right "2x-4" or "2x+4"?

Since it's perpendicular bisector, the 2 sides should be same length. So:

6x-8 = 2x-4

Then collect like terms.

'''6x-2x = 8-4 '''4x = 12 x = 3

Sub "x" back into one of the side equations:

'''side length = 2x-4  __________ = (2•3)-4  __________ = 6-4 ''' __________ = 2
