Fatima is covering her rectangular pool for the winter. The area of the cover is x² + 13x + 42 ft². The length of the cover is (x + 7) feet. A. What is the width of the cover? Make sure to include the unit of measurement. B. How did you find the width? Explain in complete sentences. C. If x = 4, what is the area of the pool cover? Show your work. Make sure to include the unit of measurement.
Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
