Step-by-step explanation:

you didn't show the actual figure but I'm going to assume the triangles are made up of a vertical of the rectangle bc of the answer choices meaning the shaded triangle is likely half the area of the rectangle

Which of the following is equivalent to the complex number -8(7i - 3i^2)

Leni [432]

Answer: B) -56i - 24

This is the same as -24 - 56i

=============================================

Explanation:

The 'i' refers to the imaginary number $\sqrt{-1}$

In other words, $i = \sqrt{-1}$

Squaring both sides gets us $i^2 = -1$

So,

$x = -8(7i - 3i^2)\\\\x = -8(7i - 3(-1))\\\\x = -8(7i + 3)\\\\x = -8(7i) -8(3)\\\\x = -56i -24 \ \ \text{ .... Answer: Choice B}\\\\x = -24 - 56i\\\\$
