Answer:
B
Step-by-step explanation:
Since the dot is not filled we can already take away c and d becuase it will not be equal to 2.
Next lets see which way its going.
The arrow goes right so it would be x>2
The answer that gives you that would be b.
Move variables to the left by adding their opposites to both sides. Eliminate the opposites.
Move constants to the right by adding their opposites to both sides. Eliminate the opposites.
Collect the like terms by subtracting their coefficients and numbers.
Calculate the sum or difference. Extract the negative sign from the expression. Add the numbers.
Divide both sides of the equation by 5 and calculate the quotient.
Simplify by opening the bracket;
x(x^2+6y^2)
=
B they only have one pair of parallel sides. The top and bottom
Circumference = 2 * pi * r, where r is the radius
For this circle, the circumference is 11pi, so 11pi=2*pi*radius. Divide both sides by 2pi and you get r is = to 5.5 inches.
Area of a circle is pi*r^2. Since we just saw that r = 5.5 inches, the circle has an area of 5.5 inches * 5.5 inches * pi or 30.25 pi inches squared.
