Answer:
D. The equation has a variable multiplied by itself. A squared variable.
Step-by-step explanation:
A quadratic equation will always start with a term being squared. For example, + 5x + 7 = 44. Another example would be + 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!

Answer:
120.105m^2
Step-by-step explanation:
Given data
Diameter of circular bed= 24+3m = 27m
radius= 27/2= 13.5
m
Diameter of side walk = 12
radius= 24= 12
m
Hence the area of the sidewalk is
Area= area of circular bed- area of side walk
Area=πR^2-πr^2
Area=π(R^2-r^2)
Area=π(13.5^2-12^2)
Area= 3.14(182.25-144)
Area= 3.14(38.25)
Area=120.105m^2
Hence the area of the side walk is 120.105m^2
