Answer:
Step-by-step explanation:
If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).

Answer:
x = -25
Step-by-step explanation:
25 = -7(x + 5) + 5x
25 = -7x - 25 + 5x
5x - 7x - 25 = 25
5x - 7x - 25 + 25 = 25 + 25
5x - 7x = 50
-2x = 50
-2x/-2 = 50/-2
x = -25
Answer:
B. 
Step-by-step explanation:
Since 3.74 is rounded to the hundredths place, it is not the ideal exact solution for m^2 = 14.
To solve for m you would have to square root m and 14, which gives you . This is the best answer for the problem.
