(x-5) = 0 or (x+2)=0
so x could be 5 or -2
i guess, u can check it with calculator
Area of a circle is directly proportional to the square of radius of the circle while the circumference is proportional to the radius of the circle. This means that if the radius of a circle is increased x times, then its area will be increased to x^2 times the original area, and the circumference will increase to x times the original circumference.
Thus when the radius is doubled, or in other words if radius mad 2 time the original radius, the area of circle will become 2^2 = 4 time the original area. The circumference will become 2 times the original circumference.
We can calculate exact area and circumference of a circle from its radius using the following equations:
Area of circle = (pi/4)*r^2
Circumference of circle = 2*pi*r
Where r is the radius of the circle.
I know this is a lot, sorry.

Answer:
The fraction of tiles that will be the color of "sand" is 23/60
Step-by-step explanation:
we know that
The sum of the fractions of the tiles must be equal to 1
Let
x ----> the fraction of tiles that will be the color of "sand"
we have that
solve for x
Find the Least Common Multiple of denominators
Multiply both sides by 60
simplify
therefore
The fraction of tiles that will be the color of "sand" is 23/60
Let x equal the number of months
Total cost=$30 + $50x
X=5 months
So total cost= 30+50(5)=$280
