Answer:
Below.
Step-by-step explanation:
a. Φ^2 − Φ − 1 = 0
Φ2 − Φ = 1
(Φ - 0.5)^2 - 0.25 = 1
(Φ - 0.5)^2 = 1.25
Φ - 0.5 = √(1.25) (We only take the positive root).
Φ = 0.5 + √(1.25)
b. I used Completing the square.
c. Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.
Answer:

Step-by-step explanation:
Measures of Chad's window is 36 inches by 60 inches = 3 feet by 5 feet.
Area of the window is 15 square feet.
Measures of Chad's door is 36 inches by 84 inches = 3 feet by 7 feet.
Area of the door is 21 square feet.
Measures of Chad's closet is 72 inches by 84 inches = 6 feet by 7 feet.
Area of the closet is 42 square feet.
Equation to show the total area of window, door and closet is 15 + 21 + 42 = 78 square feet.
