## College Algebra (11th Edition)

Set up an equation for appropriate conditions. Factor out expression and add. Subtract .84. $2(x+.42)+2x=5.96$ Divide both sides by 4 and solve for x. $4x=5.12$ Solving for x gives you the value for width. Simply add .42 to find the value for length. Don't forget to check these values by substituting them into the original equation! $x=1.28cm(width)$, $x=1.70cm(length)$
