(4d−3)+(12d+4).

To simplify the expression, we can start by combining like terms.

We have:

(4d - 3) + (12d + 4)

By adding the coefficients of the like terms, we get:

4d + 12d - 3 + 4

Combining the like terms gives:

16d + 1

Add: (2m−3)+(3n−1)+(3m+1) .(1 point)

To add the given expressions, we need to combine like terms.

We have:

(2m - 3) + (3n - 1) + (3m + 1)

By adding the coefficients of the like terms, we get:

2m + 3m + 3n - 3 - 1 + 1

Combining the like terms gives:

(2m + 3m) + 3n + (-3 + 1)

Simplifying further, we get:

5m + 3n - 2

wrong

Apologies for the mistake. Let's redo the addition correctly:

(2m - 3) + (3n - 1) + (3m + 1)

To add the expressions, we need to combine like terms:

2m + 3m - 3 + 1 + 3n - 1

Combining like terms, we get:

5m - 2 + 3n

So, the simplified expression is 5m + 3n - 2.

To simplify the expression (4d-3)+(12d+4), we can combine like terms.

First, let's focus on the terms with the "d" variable:
4d + 12d = (4 + 12)d = 16d

Now, let's look at the constant terms:
-3 + 4 = 1

Therefore, the simplified expression is:
16d + 1

To simplify the expression (4d - 3) + (12d + 4), you can start by combining like terms.

First, distribute the addition operation to remove the parentheses:

4d - 3 + 12d + 4

Next, combine the like terms:

(4d + 12d) + (-3 + 4)

Combine the coefficients of the terms with the same variable (d):

16d + 1

Therefore, the simplified expression is 16d + 1.
