ANSWER

EXPLANATION
The given geometric sequence is
400, 200, 100...
The first term is

The common ratio is

The nth term is

We substitute the known values to get;




X intercepts: (37/8,0)
y intercepts: (0,37/9)
Step-by-step explanation:
Since the polygon has four vertices (D,E,F and G), it is a quadrilateral (4 vertices).
37+n=p because all your doing is putting the numbers into a problem with the correct signs.
