Add: (4d−3)+(12d+4) . (1 point)

Answer 1

To add the two expressions, we simply combine like terms.

The first expression is 4d - 3, and the second expression is 12d + 4.

We can then add the like terms:

(4d - 3) + (12d + 4) = 4d + 12d - 3 + 4 = 16d + 1

So the sum is 16d + 1.

Answer 2

Add: (2m−3)+(3n−1)+(3m+1) .(1 point)

Answer 3

To add the three expressions, we will perform the addition operation on each term.

The first expression is 2m - 3, the second expression is 3n - 1, and the third expression is 3m + 1.

Let's add the three expressions:

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

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

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

= 5m + 3n

So, the sum of the three expressions is 5m + 3n.
