Add: (4d−3)+(12d+4). (1 point
(4d-3) + (12d+4) = 4d - 3 + 12d + 4 = (4d+12d) + (-3+4) = 16d + 1
so what is it
The simplified form of the expression (4d-3)+(12d+4) is 16d + 1.
Add: (2m−3)+(3n−1)+(3m+1).(1 point)
To add the expressions (2m-3), (3n-1), and (3m+1), you can simply add the coefficients of the like terms.
(2m-3) + (3n-1) + (3m+1)
= 2m + 3n + 3m - 3 + 1
= (2m + 3m) + 3n + (-3 + 1)
= 5m + 3n - 2
Therefore, the sum of the expressions is 5m + 3n - 2.
