Complete question:
<em>What values of c and d would make the following expression represent a real number? i(2 + 3i)(c + di)
</em>
<em>choices: A)c = 2, d = 3 B)c = –2, d = 3 C)c = 3, d = –2 D)c = –3, d = –2</em>
<em />
<em>Option D</em><em> is correct. </em> The value of c and d for the expression to be real are -3 and -2 respectively
Given the expression
Expand the expression
Collect the like terms
For the resulting function to be real, then the imaginary part must be zero i.e.
If d = -2, then;
Hence the value of c and d for the expression to be real are -3 and -2 respectively.

From the passage you learn that light pollution , caused by man-made lights , sometimes creates fogs and hazes that make the night sky look like a "dark sheet of paper".
If you compare what you understood from the passage to the alternatives , you ll realize that A) is the one that makes more sense and its more compatible with your awnser.
If you eliminated all alternatives you could but there still are 2 choices remaining and you are not sure which one it is , go back to the passage and try to find evidence for each alternative and try to eliminate one of the alternatives
AWNSER : A)
