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.
Answer:
multiply and see what you get
i think that you are multiplying them so the answer is 3553.5
and if your adding it would be 122.1
It would be 3,8

Watch this video it helped to understand how to do these
.5 -(-7) would be just 7 because of the imaginary -1 it’s being multiplied 7+1+3-7=11 then divide
