<span>so, πr^2 is the equation for the area of a circle, if we calculate that, it will equal 17662.5
we then half that to get the area (square feet) of the dead grass, which is
8831.25 square feet which means the answer is B.

Depends on the plane figure, because they have different areas.
Here are some generic formulas for different plane figures.
Square Area = b^2
Triangle Area = bh / 2
Rectangle Area = bh
Parallelogram Area = bh
Circle Area = (pi)r^2
|-5x+10| is just 5x + 10 > 10
so 5x + 10 > 10
-10 -10
5x > 0
/5 /5
x > 0 is the answer to this Inequality
hope this helps ;-)

-6x + 5 = 17
isolate the x, first subtract 5 from both sides
-6x + 5 (-5) = 17 (-5)
-6x = 12
Then divide -6 from both sides
-6x(/-6) = 12(/-6)
Answer
x = -2
hope this helps
