Answer:
12 x 6 = 72, 72 divided by 2 ( x 1/2) = 36 yd^2
Formula of a triangle:
BH x 1/2
In this case 12 is your base and 6 is your height.
2p+6a=$14
3p+9a=$21
3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations
2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14
this zeroes out...

So 20600=100%
in 2009=1.2% change from 100%
not specific whether percent change is up or down so solve fo r1.2%
d
find 1.2% of 100
percent means parts out of 1001.2%=1.2/100=0.12/10=0.012/1=0.012
'of' means multiply
20600 times 0.012=276.2
the change is 276.2
20600-276.2=20352.8
20600+276.2=20847.2
you must round down since you can't sell 0.2 or 0.8 of a car
the sold either 20,352 or 20,847 cars in 2009
