Question 1013756
You are given:
{{{ C = 4x - 3 }}}
{{{ A = 3x + 3 }}}
You need to find B
-------------------
{{{ A^2 + B^2  = C^2 }}}
{{{ B^2 = C^2 - A^2 }}}
{{{ B^2 = ( 4x-3 )^2 - ( 3x + 3 )^2 }}}
{{{ B^2 = 16x^2 - 24x + 9 - 9x^2 - 18x - 9 }}}
{{{ B^2 = 7x^2 - 42x }}}
{{{ B = sqrt( 7x*( x - 6 )) }}}
Hope this helps
