Answer: 72.5 feet squared
Step-by-step explanation:
Rectangle-Area Formula: a = lw
6 feet + 5 feet = 11 feet (length)
5 feet (width)
a = 11 * 5
a = 55 feet squared (rectangle)
Triangle-Area Formula: a = 1/2bh
2 feet (base)
5 feet (heighth)
a = 1/2 (2 * 5)
a = 5 feet squared (top triangle)
Triangle-Area Formula: a = 1/2bh
5 feet (base)
5 feet (heighth)
a = 1/2 (5 * 5)
a = 12.5 feet squared (bottom triangle)
Total Area:
Rectangle-Area + Top Triangle-Area + Bottom Triangle-Area = Total-Area
55 + 5 + 12.5 = 72.5 feet squared (total-area)

Answer:
36 feet
Step-by-step explanation:
3ft is 1 yard so you would multiply the 12 yards by 3 making 36.

Answer:
vertex: (-2, 4)
Step-by-step explanation:
Use your regression calculator to find the parameters of the quadratic model.
The vertex form equation is ...
y = -3(x +2)^2 +4
so the vertex is (-2, 4).
__
The standard form equation is the expansion of the above:
y = -3x^2 -12x -8
