Question

Combining like terms
-8(5k+9)
show how you got the answer

Answer 1

5k + 17

Explanation:

You can combine 9 and -8. 9 is positive number and you keep it where it is, then open up the parentheses and move -8 to the right but since you are moving it to the other side you have to change the sign so it would be 9 + 8 which equals 17. You can't combine 5k so you would get your answer.

(5k +17)

Answer 2

You multiply the -8 to the 5k and 9 and you will get -40K-72K
