find the area and the perimeter of the shaded regions below. give your answer as a completely simplified exact value in terms of π(no approximations). The figures below are based on semicircle or quarter circles and problems(b),(c),(d) are involving portions of a square:

The graph of the function f(x) = (x + 2)(x + 6) is shown below. which statement about the function is true? the function is positive for all real values of x where x > –4. the function is negative for all real values of x where –6 < x < –2. the function is positive for all real values of x where x < –6 or x > –3. the function is negative for all real values of x where x < –2.
