Answer:

f(- 4) = 12

Step-by-step explanation:

To evaluate f(- 4) substitute x = - 4 into f(x) , that is

f(- 4) = - 8 - 5(- 4) = - 8 + 20 = 12

f(x)=-8-5x

$\\ \rm\longmapsto f(-4)$

Put -4 inplace of x

$\\ \rm\longmapsto -8-5(-4)$

$\\ \rm\longmapsto -8+20$

$\\ \rm\longmapsto 12$

area of three triangles=3×18=54 ft²

area of sector +area of three triangles=54+9 π ft²

area of circle=π×6²=36 π ft²

area of shaded region=36 π-9π-54=27 π-54=27(π-2) ft²
