kirill [66]

<u>Answer:</u>

D. |–c| = 3 and –|d| = 4

<u>Step-by-step explanation:</u>

We are given these values of two variables and asked which of the statements in the given options is true:

c = –3 and d = 4

In mathematics, we know that the absolute value or modulus of a real number x is the non-negative value of x despite of whatever sign it has, positive or negative.

Therefore, the modulus of c  |–c| = 3 and modulus of  –|d| = 4 so option D is the correct one.
