(4d−3)+(12d+4).

Answer 1

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

Answer 2

Add: (2m−3)+(3n−1)+(3m+1) .(1 point)

Answer 3

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

Answer 4

wrong

Answer 5

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.
