To simplify the expression m(3n + 7), you need to multiply m by each term inside the parentheses (3n and 7).
To do this, you can use the distributive property, which states that a term outside the parentheses can be multiplied by each term inside the parentheses individually.
So, multiplying m by 3n gives you 3mn, and multiplying m by 7 gives you 7m.
Therefore, the simplified expression is 3mn + 7m.
Option B) 3mn + 7m is the correct answer.
