HETY is a parallelogram.
HT and EY are diagonals. We know that diagonals divides the parallelogram into two equal parts.
So ar(HET) = ar(HTY)
And, ar(HEY) = ar(EYT) now, in AHET, diagonal EY bisects the line segment HT and also the AHET,
∴ar(AHOE) = ar(AEOT)
Similarly in AETY
ar(ΔΕΟΤ) = ar(ΔΤΟΥ)
And in AHTY,
ar(ATOY) = ar(AHOY)
That means diagonals in parallelogram divides it into four equal parts.
Hence Proofed.

m is the slope
b is the y-intercept
so that means that the y-intercept of

is

Answer:
80
Step-by-step explanation:
Let the number of dogs be x.
x(75%)=60
x=60/0.75
x=80
Since we can use 91 boxes because there will be extra paperweights, we need to use 92 boxes total.
Consider that long row as 1 big rectangle with base 6+11+6+11=34 and height of 8
area=34*8=272 ft^2
the 2 rectangles on side
the sbase is 11
the height is 6 since it has to match with the other 2 side things
2*6*11=132
add to find total
132+272=404 ft^2
