Explanation:

(m+n+3)+(m+n+4)-12m+2n+7

= m+m-12m+n+n+2n+3+4+7

= -10m+4n+14

The sum of the polynomials (m + n + 3) + (m + n + 4) is 2m + 2n + 7.

The sum of the polynomials (m + n + 3) + (m + n + 4) can be found by combining like terms.

First, we can group the like terms together. The terms with "m" and "n" can be combined, as well as the constant terms 3 and 4.

So, combining the "m" terms, we have m + m, which is equal to 2m.

Similarly, combining the "n" terms, we have n + n, which is equal to 2n.

Lastly, combining the constant terms, we have 3 + 4, which is equal to 7.

Putting it all together, the sum of the polynomials (m + n + 3) + (m + n + 4) is equal to 2m + 2n + 7.

Therefore, the final answer is 2m + 2n + 7.
