Answer:
Answer choice A.
Explanation:
We can use the distributive property to solve.
4(x + 10) = 4x + 40
I got this by first multiplying 4 by x which is 4x, and 4 and 10, which is 40. We can see that 4x + 40 is one of the options here, so I would choose A. I hope this helps, and I hope it's not wrong, but I don't think it's wrong.
