Answer: 3m − 5

Explanation:

In order to find the equivalent of the expression, we just need to solve the expression by using the distribute property, which tells that a product in the form

[tex]a(b+c)[/tex]

is equivalent to

[tex]a\cdot b + a \cdot c[/tex]

So, let's apply this property. Let's rewrite the original expression first:

[tex]3(m-3)+4[/tex]

Now we apply the distributive property to the parentheses:

[tex]=3m - 3\cdot 3 +4= 3m -9+4[/tex]

By adding the last two terms,

[tex]=3m -5[/tex]
