Add: (4d−3)+(12d+4) . (1 point)
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.
Add: (2m−3)+(3n−1)+(3m+1) .(1 point)
To add the given expression, we combine like terms.
First, let's simplify the expression within the parentheses: (4d - 3) + (12d + 4)
To add the like terms, we sum the coefficients of the variable 'd'.
The coefficient of 'd' in the first term is 4, and the coefficient of 'd' in the second term is 12.
So, 4d + 12d = 16d.
Next, let's simplify the constant terms: -3 + 4 = 1.
Now we have: 16d + 1
Therefore, the simplified expression is 16d + 1.
To add the expressions (4d - 3) and (12d + 4), you need to combine the like terms, which means adding the coefficients of the variables with the same exponent.
Given:
(4d - 3) + (12d + 4)
Step 1: Simplify within each set of parentheses:
4d - 3 = 4d - 3
12d + 4 = 12d + 4
Step 2: Remove the parentheses:
(4d - 3) + (12d + 4) = 4d - 3 + 12d + 4
Step 3: Combine the like terms:
4d + 12d -3 + 4 = (4d + 12d) + (-3 + 4) = 16d + 1
The final answer is 16d + 1.
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.
