Answer 1

Answer:

-45k+90

Step-by-step explanation:

Re-order terms so constants are on the left

(5k-10)  · -9

-9(5k-10)

Distribute

-9(5k-10)  

[-9 · 5k = -45k]                              Negative + Positive = Negative

[-9 · -10 = 90]                                Negative + Negative = Positive

-45k+90

Hence, -45k+90  is the Answer.
