Answer:
Take the coordinates of each vertex (corner point) and subtract 2 from the x-coordinate; leave the y-coordinate alone.
Step-by-step explanation:
Example: If one vertex is the point (5, 3), then it moves left 2 units to (3, 3).
If a vertex is at (-3, 1), then it moves 2 units left to (-5, 1).
Answer:

Step-by-step explanation:
Having the radius to be involved, the shape is a circle.
<u>Circumference formula </u>

Finding radius, formula will be reversed.


Well 5+2 is 7 and 51/2+21/7 is 57/2
48=x+y
143= 2x+4y
y= sheep
48-y = x
143=2(48-y)+4y
143= 96-2y+4y
143=96+2y
47=2y
y=19
19 sheep
I think the answer is C and D..searched it up
