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
Answer:
-81
Step-by-step explanation:
f(x) = 8x -1
f(-10) = 8(-10) -1
f(-10) = -80-1
f(-10) = -81
Given,
The expression is:

By using the middle term splitting method,

Hence, the factor is (x-(7+sqrt(33)/4)) (x+(7+sqrt(33)/4)).
