Algebra.Com's Answer #104173 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! the distance between the foci is 4, so c=2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "b^2=a^2-c^2 __ b^2=36-4 __ b^2=32 (not 22)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "[(x+4)^2]/36+[(y-5)^2]/32=1 __ multiplying by 36*8 (LCM) __ 8(x+4)^2+9(y-5)^2=36*8 \n" ); document.write( " |
