Answer:
51.63
Step-by-step explanation:
100.00
- 48.37
______
51.63
______
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
Answer:

Step-by-step explanation:
5(2x²-1)+3(7x²+1) = 5*2x² - 5*1 + 3*7x² + 3 = 10x² - 5 + 21x² + 3 = 31x² - 2
The model that is equivalent is a
