Answer
The answer is -43.
Step-by-step explanation
The question wants us to evaluate the expression using the given variables
-k² - (2k - 5n) + 3n
if k = -3, n = -5
So, to solve this, we would just substitute the given values for k and n
-k² - (2k - 5n) + 3n
= -(-3)² - [(2 × -3) - (5 × -5)] + (3 × -5)
= -(9) - [-6 - (-25)] - 15
= -9 - (-6 + 25) - 15
= -9 - (19) - 15
= -9 - 19 - 15
= -43
