Answer:
9
Step-by-step explanation:
They both have -10 so just compare 3 and 12. Thats a difference of 9.
I would say D, determine if it can be factored by grouping (sorry, I forgot to put in the answer here).
I think Great Falls' average wind speed is greater than Chicago's by 2.7 miles
2. 225
4. 25/36
6. 0.001
8. 8-20=-12
10. 34-16=18
12. 15/5=3^3=27
14. ?? confused...
16. 8
18. 11.5+4=15.5
20. 3(225)+10=675+10=685
Area=lw
l=2w
aera=2l^2
72=area
72=2l^2
divide both sides by 2
36=l^2
sqrt both sides
6=l
length=6 units
