The area of the trapezoid is given by:
 A = (1/2) * (b1 + b2) * (h)
 Where,
 b1, b2: bases of the trapezoid
 h: height
 Substituting values we have:
 91 = (1/2) * ((2 * 7) + b2) * (7)
 Rewriting we have:
 91 = (1/2) * (14 + b2) * (7)
 (2/7) * 91 = 14 + b2
 b2 = (2/7) * 91 - 14
 b2 = 12 m
 Answer:
 The measure of the other base of the trapezoid is:
 b2 = 12 m
        
                    
             
        
        
        
Graph is accurate enuf so that you can determine immed that the vertex / minimum is at (3,-4) and that the y-intercept is at (0,5).
If by "solutions" you mean "roots," the roots are {1, 5} (where y=0).
        
             
        
        
        
Answer: -2x
X being how tall each level is
If you don't have that information it would just be
