Answer:
Area of Shaded Region 
Area of Semicircle 

Step-by-step explanation:
Area of Shaded Region = Area of Sector - Area of Semicircle
<u>Area of Sector</u>
Radius of the sector =20cm

<u>Area of Semicircle</u>
Since AB is the diameter of the semicircle
Radius of the Semicircle=20/2=10cm
Area of semicircle

Therefore, area of Shaded Region

Area of Square =20 X 20 

Answer:
y=-3x-12
Step-by-step explanation:
Plug into equation y=mx+b
3=(-3)-5+b
Simplify
3=15+b
Subtract 15 from both sides
-12=b
Add slope and y-intercept into base equation
y=-3x-12
