6x -24y, B.

Answer 3

Would you mind explaining how you got to that?

Answer 4

Let's simplify step-by-step.
−3(10x+4y)+6(6x−2y)
Distribute:
=(−3)(10x)+(−3)(4y)+(6)(6x)+(6)(−2y)
=−30x+−12y+36x+−12y
Combine Like Terms:
=−30x+−12y+36x+−12y
=(−30x+36x)+(−12y+−12y)
=6x+−24y

Answer 5

Answer:
=6x−24y, B.
