Answer:
2x-0=x+2
2x=x+2
2x-x=2
x=2
4y-8=y+10
4y-y=10+8
3y=18
y=6
AB=2×2+0=4 (DC is 4 too)
AD=4×6-8=24-8=16 (BC is 16 too)
So originally, let's say the width of Frank's land was

feet.
The area of his land was therefore

, or

, as his land was square.
The width of his land then increased by 3 feet, and the height decreased by 3 feet.
So the new area of Frank's land is:

So the new land is now
9 square feet smaller, so it is not a fair deal for Frank.
Hope this helps :)
14.42 is your distance formula
(1,0) is the midpoint
if you need the forma for distance it is x2-x1 squared + y2-y1 squared then square root it
First basically solve.
Next, take the number after the decimal point and see if it's larger than 5 or lesser than 4.
Than, Look at the number before the decimal point and relate back to step 2 (Next) if the number is higher than one. Add by 1 to the number before the decimal.
Example:
4.45
vvvv
4.(4)5 > The 4 is lesser than 4, so the number before the decimal point is keep the same.
vvvvvvv
