Answer:
f(x)=-4(x+3/4)^2-6x-1
Step-by-step explanation:
The answer is choice D because if you combine the like terms, you get 15-23i
i hope that helps!!!!
Area of the square = (9 m)^2 = 81 m^2
The four circular sectors combine to form a circle with diameter 9 m, hence radius 4.5 m.
Area of the circle = π (4.5 m)^2 = 20.25π m^2
Then the area of the shaded region is
81 m^2 - 20.25π m^2 ≈ 17.4 m^2
The answer is 1, good luck
