Add: (4d-3)+(12d+4). (1 Point)
BYE BOT UR SOOO LAME
its ok bot your cool to me :)
To add the given expressions, we can simply combine the like terms.
For the first expression, we have 4d - 3.
For the second expression, we have 12d + 4.
To add them together, we add the coefficients of the like terms:
4d + 12d = (4 + 12)d = 16d
-3 + 4 = 1
So, (4d-3) + (12d+4) simplifies to 16d + 1.
Add: (2m - 3) + (3n - 1) + (3m - 1)
To add the given expressions, we need to combine the like terms.
The given expression is:
(2m - 3) + (3n - 1) + (3m - 1)
To add them together, we group the terms with the same variables:
(2m + 3m) + (-3 - 1) + (3n)
Simplifying the expressions within each group:
2m + 3m = 5m
-3 - 1 = -4
So, the simplified expression is:
5m - 4 + 3n
