8minutes-2minutes=6minutes
6×80 copies = 480 copies
To answer this question you would need to know the formula for the area of a circle,

. You would start by squaring 400, getting 160,000. You would then multiply 160,000 by 3.14, getting 502,400 meters squared as your answer.
Multiply -3[4x+y=6].
This gets you -12x-3y=-18.
Add the two equations together to eliminate the y.
-12x - 3y = -18
+ 12x + 3y = 18
------------------------
0 = 0
This means that these are in fact the same line, therefore there are infinite solutions.
