Answer:
3 vertices
Step-by-step explanation:
Vertices are the "points" of a 2D figure. In this case, we see the 2D figure as a triangle. There are 3 points on the triangle, so there are 3 vertices.
3 1/2 is equal to 7/2. 1 1/2 is equal to 3/2. 7/2 times 3/2 is equal to 21/2, which is equal to 10 1/2.
A. The hexagon as the series is adding a side each time. So you started with 3, 4, 5...
5x - 3y = -11 (×2)
2x - 6y = -14 (x5)
10x - 6y = -22
10x - 30y = -70
---------------------- -
24y = 48
y = 2
