Answer:

Step-by-step explanation:
A = the area of the region outside the semicircle but inside the rectangle
w = the width of the rectangle or diameter of the semicircle
Since "A" is determined by "w", therefore, "A" is a function of "w" = A(w).
A(w) = (area of rectangle) - (area of semicircle)

Where,
lenght of rectangle (l) = w + 5
width of rectangle (w) = w
r = ½*w = 
Plug in the values:


Simplify





Answer:
A(2,5)
Step-by-step explanation:
x=2 and y=5
2y+4x=18
2y-3x=4
2(5) + 4(2) = 18
10+8=18
2(5)-3(2)=4
10-6=4
