Answer:

C. 40-4x-12x^2

Step-by-step explanation:

? – (20 – 4x – 5x2) = 20 – 7x2, so ?  = 20 – 7x2 + (20 – 4x – 5x2)

?  = 20 – 7x2 + (20 – 4x – 5x2)=20-7x²+20-4x-5x²=40-12x²-4x

sveticcg [70]

Answer:

12.86 sq ft

Step-by-step explanation:

Find area of square and subtract out area of semi-circle; the diameter of the semi-circle equals the side of the square, which is 4 so radius is 2

A(square) = 4 x 4 = 16

A(semi-circle) = πr²/2

= 4π/2 or 2π

Area of Shaded Region = 16-3.14 which is 12.86
