Add: (4d − 3) + (12d + 4). (1 point)
To add the expressions (4d − 3) and (12d + 4), we combine the like terms.
The like terms in this case are the terms with the variable 'd'.
So, we have:
4d + 12d - 3 + 4
Combining the like terms, we get:
(4d + 12d) + (-3 + 4)
Simplifying further, we have:
(16d) + (1)
Therefore, the sum of (4d − 3) and (12d + 4) is 16d + 1.
