Which of the following are terms in this expression? Select all that apply.

Question

6mn+2n+7kn+8
K
7k
2n
M

Answer 1

In the expression \( 6mn + 2n + 7kn + 8 \), the terms are the parts of the expression that are separated by plus or minus signs.

The expression consists of four terms:

1. \( 6mn \)
2. \( 2n \)
3. \( 7kn \)
4. \( 8 \)

Now, looking at the provided options:

• \( K \) (not a term)
• \( 7k \) (not a term, \( 7kn \) is the actual term)
• \( 2n \) (this is a term)
• \( M \) (not a term)

So the only correct option that is a term in the expression is:

• \( 2n \)
