Algebra.Com's Answer #208042 by unlockmath(1688)![]() ![]() You can put this solution on YOUR website! Hello, \n" ); document.write( "Since we know volume = width times length times height let's have \"x\" be the width. Therefore the equation will be: \n" ); document.write( "x(x+5)27=4050 Expand this out to: \n" ); document.write( "27x^2+135x=4050 Subtract 4050 from both sides to get: \n" ); document.write( "27x^2+135x-4050=0 Take 27 out to be: \n" ); document.write( "27(x^2+5x-150)=0 Factor this to get: \n" ); document.write( "27(x-10)(x+15)=0 solve x: \n" ); document.write( "x=10 \n" ); document.write( "x=-15 \n" ); document.write( "x=10 is the only reasonable answer so the answer is: \n" ); document.write( "10 inches for the width and you can now get how high it is. \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "Check out a new book: \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
