Answer:
The correct answer is 3 × 5 + 3 × 7 + 6 × 7 = 78 square feet.
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.
The ordered pairs of the solution to the system of equation are [(3, 6), (-3, 18)]
<h3>System of equations</h3>
Given the following system of equations expressed as:
f(x) = x² - 2x + 3 and f(x) = -2x + 12
Since they are both function of x, hence;
x² - 2x + 3 = -2x + 12
x² - 2x + 3 + 2x - 12 = 0
x² - 9 = 0
x² = 9
x = ±√9
x = ±3
If x = 3
f(x) = -2(3) + 12
f(x) = 6
If x = -3
f(x) = -2(-3) + 12
f(x) =18
Hence the ordered pairs of the solution to the system of equation are [(3, 6), (-3, 18)]
