Final answer:
The value of A in the given equation is 222.
Step-by-step explanation:
The expression A = 1/2(7*7 + 5*5)6 represents a mathematical equation. Let's solve it step by step:
- Start by evaluating the expressions inside the parentheses: 7*7 = 49 and 5*5 = 25.
- Add the results: 49 + 25 = 74.
- Multiply the sum by 1/2: 1/2 * 74 = 37.
- Multiply the final result by 6: 37 * 6 = 222.
Therefore, the value of A is 222.
