Answer:
4. About 2,700 in2
Step-by-step explanation:
The area of a circle (
), measured in square inches, is directly proportional to the square of its diameter (
), measured in inches. That is:
Where 
is the constant of proportionality, dimensionless.
In consequence, the following relationship between circles A and B is obtained:
The area of the circle B is now cleared:
Given that 
, 
and 
, then:
Therefore, the correct answer is 4.
Let's try the actual solution of the system
<span>y = –2x + 1
y = –2x – 3
Note that the slopes of the graphs of these two lines are the same: -2.
That means that the lines are parallel to one another.
Only the y-intercepts (1 and -3) are different.
Since the 2 lines never intersect, the system has no solution.

Answer:
The answer is 45.72
Step-by-step explanation:
If 1 yard = 2.54 centimeters, you multiply each side by 18.
1*18=18
2.54*18=45.72.
18 yards=45.72 centimeters.
The lcd would be 10x^3y^3
