document.write( "Question 524722: The length of the base of a triangle is six times its height. If the area of the triangle is 75 square kilometers. find the height (A = 1/2 b h)\r
\n" );
document.write( "\n" );
document.write( "I got the height = X
\n" );
document.write( "and the base 6x
\n" );
document.write( "every time i plug it in i am getting 75 = 1/2 (6x)(x)
\n" );
document.write( "75 = (3x)(x2) then 0 = x2 +3x-75 and now i am stuck on (x+ )(x- ) can you please tell me where i am messing up thank you \n" );
