Answer:
sorry but I don't know the answer for this
Answer:
Canada was 418.912 sq miles smaller than the USSR.
Step-by-step explanation:
Note: I don't know if this question required a calculator so I'll answer without one.
Symbols:
- USSR area in sq miles = u
- Canada area in square miles = c
u<em> </em>= 8.649×106
c<em> </em>= 4.797×106
x = how much less area
u<em> </em>= c + x
- USSR area = Canada area + number of sq miles less
Math:
u = c + x
8.649×106 = 4.797×106 + x
- divide by 106 to get rid of the ridiculously large numbers.
8.649 = 4.797 + 
- subtract (use calculator or just traditional subtraction methods)
3.952 = 
- multiply both sides by 106 (use calculator or traditional methods)
418.912 = x

2n2 i’m gonna assume is 2n^2
and n2 is 2n
2n^2-10n+5
=(-17) - 4
=(-17) + (-4)
=(-21)
The answer is c because all you are doing here is subbing the variable r for 5b.
