You can put this solution on YOUR website!
Let h=height, s=side of square base
\n" ); document.write( "Using the word problem as the clue to what h equals we see that
\n" ); document.write( "\"h=68%2B3s\"
\n" ); document.write( "If the sum of the height and the side is 1380 it translates to this:
\n" ); document.write( "\"h%2Bs=1380\"
\n" ); document.write( "Plug in 68+3s into h
\n" ); document.write( "\"%2868%2B3s%29%2Bs=1380\"Solve for s
\n" ); document.write( "\"68%2B4s=1380\"
\n" ); document.write( "\"4s=1312\"
\n" ); document.write( "\"s=328\"
\n" ); document.write( "So the side's length is 656 ft, use this to find the height
\n" ); document.write( "\"h=68%2B3s\"
\n" ); document.write( "\"h=68%2B3%28328%29\"
\n" ); document.write( "\"h=68%2B984\"
\n" ); document.write( "\"h=1052\"
\n" ); document.write( "So the height of the tower is 1,052 ft tall
\n" ); document.write( "Check:
\n" ); document.write( "\"h%2Bs=1380\"
\n" ); document.write( "\"1052%2B328=1380\"
\n" ); document.write( "\"1380=1380\"works
\n" ); document.write( "
