add (4d -3) + (12d + 4)
When we add like terms, we combine the coefficients of the same variables.
(4d - 3) + (12d + 4)
= 4d + 12d - 3 + 4
= (4d + 12d) + (-3 + 4)
= 16d + 1
Therefore, the expression (4d - 3) + (12d + 4) simplifies to 16d + 1.
(4d - 3) + (12d + 4)
= 4d + 12d - 3 + 4
= (4d + 12d) + (-3 + 4)
= 16d + 1
Therefore, the expression (4d - 3) + (12d + 4) simplifies to 16d + 1.
