Lets get an example, for this example lets use 24/30 x 30/60
Without dividing out GCFs you would get 24x12 over 30 x 60 which is 288/1800
With dividing out GCFs you get 2/1 x 5/1 Which is 7 :)
Your answer is the matrix with the top row of -8 20 0 and bottom row of
4 32 -4
The answer would be a hope it helps
C because u can split it only once vertically but it’s not a rotationally symmetrical shape
