Question

Evaluate - 2(3k+9x) when k= -8 and x= -9

Answer 1

210

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.
