Step-by-step explanation:
This expression was kind of trial and error for me seeing as I'm not really good at logic, but this is pretty basic. There are three possible places the parentheses can be placed (assuming each pair holds 2 terms);
The answer to the first expression would be 45, which is not equal to 11.
The answer to the second expression would be 15, which is also not equal to 11.
The answer to the last expression is 11, so that is the correct answer.
Hope this helped :D

When we connect the ends of the poles and the project the horizontal line from the end of the 10-ft pole to the other pole, we form a right triangle with the legs equal to 12 ft and difference of the lengths of the pole. Using the Pythagorean theorem,
h² = sqrt ((12 ft)² + (15 - 10)²)
h = 13 ft
Thus, the distance between the tops of the poles is equal to 13 ft.
