I got -6/25 Sorry I can't really explain this try web2.0calc.com it helps alot with math.
It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.
The area of a square is given by the equation

The area of this square is 576cm2.
Hope this helps!
Answer:
if
is divided by
, the remainder is -9
Step-by-step explanation:
We need to find the remainder if
is divided by 
Dividing
by 
The division is shown in figure attached.
The remainder = -9
The quotient = x+3
So, if
is divided by
, the remainder is -9
Distribute first.
.75 times 8 + .75 times e, which is 6+.75e = 2-1.25e
Then subtract 2 from both sides,
4+.75n=-1.25e
Next subtract .75 from both sides,
4=-2e
Divide both sides by -2, and you will get e= -2. Hope this helps!
