Solve this for me please it would be very much appreciated

x= 8

Step-by-step explanation:

Right angled triangle :

Use Pythagorean theorem,

Base² + altitude² = hypotenuse²

x² + ( 2x - 1)² = (2x +1)²

(2x + 1)² - (2x-1)²  -x² = 0

      {here, a = 2x and b = 1}}

4*2x*1 - x²= 0

8x - x² = 0

x(8 - x) =0

x = 0  {Ignore}  or 8 - x= 0

                  -x = -8

                   x = 8

x = 8
