To simplify the expression \((2 + 5)^2 - 42\):

1. **Calculate the parentheses first**:
\(2 + 5 = 7\).

2. **Square the result**:
\(7^2 = 49\).

3. **Subtract 42**:
\(49 - 42 = 7\).

The result is \(7\), which corresponds to **option A**.

doubao C

First calculate (2+5)^2 = 7^2 = 49, then 49 - 42 = 7. So the answer is C.		 A
minimax First, we need to calculate the square of the binomial (2 + 5)^2:

(2 + 5)^2 = 7^2 = 49

Now, we subtract 42 from the result:

49 - 42 = 7

Therefore, the answer is:

A. 7		 A
kimi First, simplify the expression inside the parentheses:
