If A={3,5,7,9,11}, then write which of the following statements are true. If a statement is not true, mention why.
`5,9inA`

Answer

To determine whether the statement "5, 9 in A" is true, we will follow these steps:

### Step 1: Identify the Set
We have the set A defined as:
\[ A = \{3, 5, 7, 9, 11\} \]

### Step 2: Check the Elements
We need to check if the elements 5 and 9 are present in the set A.

### Step 3: Verify Element 5
Look for the number 5 in the set A:
- The set A contains the number 5.

### Step 4: Verify Element 9
Now, look for the number 9 in the set A:
- The set A also contains the number 9.

### Step 5: Conclusion
Since both 5 and 9 are present in the set A, we can conclude that the statement "5, 9 in A" is true.

### Final Statement
The statement "5, 9 in A" is true because both elements 5 and 9 are included in the set A.
