If `a o+ b = (a +b) (a xx b)` then find the value of `6o+ 5.`

Options

A. 110
B. 220
C. 330
D. 440

Answer

To solve the problem where we need to find the value of \( 6 o + 5 \) given the operation defined as \( a o + b = (a + b)(a \times b) \), we can follow these steps:

### Step 1: Identify the values of \( a \) and \( b \)
In our case, we have:
- \( a = 6 \)
- \( b = 5 \)

### Step 2: Substitute the values into the operation
We substitute \( a \) and \( b \) into the operation:
\[ 6 o + 5 = (6 + 5)(6 \times 5) \]

### Step 3: Calculate \( 6 + 5 \)
Now, we calculate \( 6 + 5 \):
\[ 6 + 5 = 11 \]

### Step 4: Calculate \( 6 \times 5 \)
Next, we calculate \( 6 \times 5 \):
\[ 6 \times 5 = 30 \]

### Step 5: Substitute back into the expression
Now we substitute these values back into our expression:
\[ 6 o + 5 = 11 \times 30 \]

### Step 6: Calculate the final result
Finally, we calculate \( 11 \times 30 \):
\[ 11 \times 30 = 330 \]

### Conclusion
Thus, the value of \( 6 o + 5 \) is \( 330 \).
