cuirass of the falling star If the area of the rectangle is 60 centimeters squared, which equation models the situation correctly? Answer by jorel555(1290) (Show Source): You can put this solution on YOUR website! If the length is l, then w, width, equals l-4. So your equation looks like: A=l x w 60= l(l-4) Solving, we get:Equations: y= x^2-2x+3 y=2x+4. Inequalities: y≥3x^2+2 y<2x+6. The only possible answers for the systems of equations are the two set intersections, while the possible answers for the systems of inequalities are in the range where both equations' shaded areas are overlapping.
