Just multiply $20 with $75 (oh by the way, thr money sign goes first!)
Answer:
y = x² - 2x - 3
Step-by-step explanation:
y + 4 = C(x - 1)²
To determine C, use x = 4, y = 5
5 + 4 = C(4 - 1)²
9 = 9C, C = 1
y + 4 = (x - 1)² = x² - 2x + 1
y = x² - 2x - 3
The area of a triangle in determined by the formula:

where b is the base of the triangle and h is it's height
You just have to replace the b and h with their values in the formula (b=9.9ft and h=5.5ft)
The answer is 27.225 ft^2
66 minutes is the correct answer
