A. Area of ABCD - Area of DGA = Area of DEFG
 s^2 - 1/2bh = s^2
 (5)^2 - 1/2(4)(3) = (3)^2
 25 - 1/2(12) = 9
 25 - 24 = 9
 1 not equal to 9
B. Area of ABCD - Area of GHIA = Area of DGA
 s^2 - s^2 = 1/2bh
 (5)^2 - (4)^2 = 1/2(4)(3)
 25 - 16 = 1/2(12)
 9 not equal to 6
C. Area of ABCD + Area of DGA = Area of GHIA
 s^2 + 1/2bh = s^2
 (5)^2 + 1/2(4)(3) = (4)^2
 25 + 1/2(12) = 16
 25 + 6 = 16
 31 not equal to 16
D. Area of DEFG + Area of GHIA = Area of ABCD
 s^2 + s^2 = s^2
 (3)^2 + (4)^2 = (5)^2
 9 + 16 = 25
 25 = 25
The answer is D.
        
                    
             
        
        
        
Answer:
D 
Step-by-step explanation:
choice A is not guaranteed since the values varied from 0 to 7.
choice B seems alright, but doesn't include about or anything about the long run.
choice C is incorrect because 50% are less than 3.12 and 50% are greater than 3.12.
choice D seems pretty good, since it says average, long run, approach, etc.
choice E is incorrect because it says "will be". It is not definite.
