Add: (4d − 3)+(12d + 4) .
To add the two expressions, we simply combine the like terms.
(4d - 3) + (12d + 4)
= 4d + 12d - 3 + 4
= (4d + 12d) + (-3 + 4)
= 16d + 1
So, the sum of (4d - 3) and (12d + 4) is 16d + 1.
(4d - 3) + (12d + 4)
= 4d + 12d - 3 + 4
= (4d + 12d) + (-3 + 4)
= 16d + 1
So, the sum of (4d - 3) and (12d + 4) is 16d + 1.
