Answer:
B) n + 16
Step-by-step explanation:
We are given the expression 9 + 7 + n.
Here we need to simplify.
Simplify means we need to simplify the like terms.
Let's see what a like term is.
If we have the same variable with the same exponent, then they are called like terms.
The constants are the like terms, we can simplify them.
Examples:
2xy, -3xy are the like terms
[tex]5xy^2, -8xy^2[/tex] are like terms
4, 5, -7, 8 are the like terms.
In the given expression 9 + 7 + n
The like terms are 9 and 7. There are in the operation of addition. So we can add them.
So, 9 + 7 + n
= 16 + n
This can be written as n + 16 by commutative property of addition.
Therefore, the answer is B) n + 16
