Answer:
210
Step-by-step explanation:
When you have questions that says evaluate [insert equation here] and it gives you variables thats inside the equation, replace the equation with that value.
The question is telling you that k is equal to -8 and x is equal to -9. So replace k and x with their numerical values so you can proceed with math.
-2(3k+9x) turns into: -2(3(-8)+9(-9)).
-2(3k+9x) (or -2(3(-8)+9(-9))) evaluates to 210.
