IF EC = 8, than we know for sure that the length of AC would be 2 x 8 = 16

The formula to use in determining Rhombus area is 
A = (AC . DB)/2 , so the value x could be found with this equation :

72 = 16 (x-1)     /  2

72 = (16x -16) /2

72 = 8x - 8

80 = 8x 

x = 10

Answer:

A, 2 5/8 cups

Step-by-step explanation:

Since six dozen brownies is three times as much as two dozen, we can multiply 7/8 cups by 3. 3 x 7/8 = 21/8 If we simplify this fraction, it is 2 5/8. Therefore the answer is A, 2 5/8 cups.
