Check the picture below.
you can pretty much count those lengths off the grid.
recall that A = 1/2 bh.
Combine like terms. Is there a picture for this?
-4(-5) = -4*-5 = 20
6 - (-4) = 10
Quotient = 20 /10 = 2 answer
The answer is 20 y=9 times that and y= 9 times that also u subtract and then u get 20.
