with the distributive law, every term in the first multiplier needs to multiply every term in the second multiplier.

a * (b + c) = (a * b) + (a * c)

(a + b) * (c + d) = (a * c) + (a * d) + (b * c) + (b * d).

in this problem:

2 * (x + 5) should be (2 * x) + (2 * 5).

selection B is your solution.
