Answer:
the outside fence has a 64 feet perimeter
Slope intercept form is y=mx+b. In this case, I believe it's y= -5/6x -5/6.
The area of a paralellogram is bh
each dimention is multiplied by n
b turns to bn
h turns to hn
bh turns to (bn)(hn) or bnhn or bhn²
expression is bhnn or bhn² or bhn^2 (depends if the program will let you enter the exponent)
25÷100=0.25
0.25×680=170 is the answer
Then it is $19:99 per chesse piece
