Hi there!
There are several possible options.
A main one would be : 10 DIMES and 2 PENNIES
Other ones could be :
2 quarters
1 dime
2 pennies
62 pennies
12 nickels
2 pennies
and more !
Hope this helps !
4y+8x+2=0
-4y. -4y
8x+2=-4y
Divide by -4 on both sides
-2x-2/4= y
Y= -2x-2/4
The slope is -2
Since it is a field is in a shape of a rectangle, there is 4 sides. I did 200/4 and got 50ft for each side. If you don't think that is true, see for yourself.
