Final answer:
The sum of 3 times m and 4 times m is 7m, which you find by adding the coefficients of the like terms.
Step-by-step explanation:
The sum of 3 times m and 4 times m can be determined using basic algebraic addition. To find this sum, you simply add the two expressions together: 3m + 4m. To add these terms, you combine the like terms which both have the variable m. The coefficients (the numbers in front of the m's) are added together, resulting in 7m. Therefore, the sum of 3 times m and 4 times m is 7m.
