Answer:

33.72

Step-by-step explanation:

To figure out the answer, we need to find the total area of the rectangle, and then subtract the blank shape.

Lets first find the area of the rectangle. 4x10=40

Lets now find the area of the blank shape. We fill caculate the area of the circle and then divide by 2 because it is a half circle. 4/2=2. 2x2=4. 4x3.14= 12.56/2=6.28

40-6.28= 33.72

Form a polynomial f(x) with real coefficients having the given degree and zeros.
dimaraw [331]
There are many polynomials that fit the bill,
f(x)=a(x-r1)(x-r2)(x-r3)(x-r4)  where a is any real number not equal to zero.
A simple one is when a=1.
where r1,r2,r3,r4 are the roots of the 4th degree polynomial.
Also note that for a polynomial with *real* coefficients, complex roots *always* come in conjugages, i.e. in the form a&pm;bi  [&pm;=+/-]

So a polynomial would be:
f(x)=(x-(-4-5i))(x-(-4+5i))(x--2)(x--2)
or, simplifying
f(x)=(x+4+5i)(x+4-5i)(x+2)^2
=x^4+12x^3+77x^2+196x+164   [if you decide to expand]
