If the sides of a square are increased by 3 inches., the area becomes 64 inches^2. Find the length of a side of the original square.
\n" ); document.write( ":
\n" ); document.write( "Let x = side of the original square
\n" ); document.write( "Then
\n" ); document.write( "(x+3) = side of the new square with an area of 64 sq/in
\n" ); document.write( ":
\n" ); document.write( "A simple equation:
\n" ); document.write( "(x+3)^2 = 64
\n" ); document.write( ":
\n" ); document.write( "Conveniently we can find the square root of both sides easily 8*8 = 64, right
\n" ); document.write( "x + 3 = 8
\n" ); document.write( "x = 8 - 3
\n" ); document.write( "x = 5 inches is the length of the side of the original square
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "(5+3)^2 = 64, right?
