You can put this solution on YOUR website!
let f = father's age
\n" ); document.write( "let d = daughter's age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "A father is four times as old as his daughter.
\n" ); document.write( "f = 4d
\n" ); document.write( ":
\n" ); document.write( " The sum of the squares of their ages is 1088. Find their ages.
\n" ); document.write( "f^2 + d^2 = 1088
\n" ); document.write( "replace f with 4d
\n" ); document.write( "(4d)^2 + d^2 = 1088
\n" ); document.write( "16d^2 + d^2 = 1088
\n" ); document.write( "17d^2 = 1088
\n" ); document.write( "d^2 = 1088/17
\n" ); document.write( "d^2 = 64
\n" ); document.write( "d = \"sqrt%2864%29\"
\n" ); document.write( "d = 8 yrs is the daughter's age
\n" ); document.write( "I'll let you find Dad's age, check your solutions in the 2nd equation \n" ); document.write( "
\n" );
