What is the main point of the stanford prison experiment? select one: a. students cannot be trusted in roles of authority b. zimbardo was an unethical researcher c. students cannot be relied upon to act appropriately d. social roles are powerful determinants of human behavior?

The right answer is d. social roles are powerful determinants of human behavior. The Stanford prison experiment was conducted by Philip Zimbardo, which consisted of separating a group of university students between prisoners and prison guards, in order to know how social roles determined human behavior. The experiment had to be suspended because its ethics were questioned.

I hope my answer can help you.

1. Width = x + 2

2. Length = 12; width = 9

3. x² + 7x + 10

4. 108

Step-by-step explanation:

perimeter = 4x + 14

length = x + 5

1. Perimeter of a rectangle = 2(length + width)

4x + 14 = 2{(x + 5) + width}

4x + 14 = 2x + 10 + 2width

4x + 14 - 2x - 10 = 2width

2x + 4 = 2width

Width = (2x + 4)/2

Width = x + 2

2. Perimeter of a rectangle = 2(length + width)

42 = 2{(x + 5) + (x + 2)}

42 = 2x + 10 + 2x + 4

42 = 4x + 14

42 - 14 = 4x

28 = 4x

x = 28/4

x = 7

length = x + 5

= 7 + 5

= 12

Width = x + 2

= 7 + 2

= 9

3. Area of the rectangle = length × width

= (x + 5)(x + 2)

= x² + 2x + 5x + 10

= x² + 7x + 10

4. Area of the rectangle = x² + 7x + 10

When x = 7

x² + 7x + 10

= 7² + 7(7) + 10

= 49 + 49 + 10

= 108
