Final answer:
The value of the expression -a² - 2bc - c is -19.
Step-by-step explanation:
To evaluate the expression -a² - 2bc - c with the given variable replacements, we substitute the values of a, b, and c into the expression. Since a = -2, b = 3, and c = -3, we have:
-(-2)² - 2(3)(-3) - (-3)
= -4 - 18 + 3
= -19
Therefore, the value of the expression is -19.
