1. A rectangle has a length that is 2 units longer than the width. If the width is increased by 4 units and the length is increased by 3 units, write two equivalent expressions for the area of this new rectangle.
2. A vacant rectangular lot is being turned into a community vegetable garden with a uniform path around it. The area of the lot is represented by the equation 4x^2+40x=44 where x is the width of the path in meters. Find the width of the path surrounding the garden.
3. The are of the trapezoid is found using the formula " A= 1/2h(b(1)+b(2)), where A is the area, h is the height, and b(1) and b(2) are lengths of the bases. (Base of the trapezoid is "b(2)=x+7", the height of the trapezoid is "h=4" and the top part of the trapezoid is "b(1)=x-3". ) Write 2 equivalent expressions for the area of the trapezoid.
