Answer: C) 1560
Step-by-step explanation:
So the first part is splitting the rectangle from the triangle so the area for the rectangle is 1440 (40 x 36) and the area for the triangle is 120 ((6x40)/ 2)
when you add them up the equal 1560 (1440 + 120)

By the polynomial remainder theorem, because <em>x</em> = 2<em>i</em> is a zero of <em>f(x)</em>, we have no remainder upon dividing <em>f(x)</em> by <em>x</em> - 2<em>i</em>.
Computing the quotient yields
![\dfrac{x^4+x^2+a}{x-2i} = x^3+2ix^2-3x-6i+\dfrac{12+a}{x-2i}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E4%2Bx%5E2%2Ba%7D%7Bx-2i%7D%20%3D%20x%5E3%2B2ix%5E2-3x-6i%2B%5Cdfrac%7B12%2Ba%7D%7Bx-2i%7D)
Then if the remainder term is 0, follows that <em>a</em> = -12.
