Answer:
Step-by-step explanation:
The range of a function is the set of y values for which the function is defined.
In simpler words, the beginning of the range is the y value of the lowest point on the graph, and the ending of the range is the y value of the highest point on the graph.
For this problem, the graph reaches down to -5 and up to 5.

Answer:
(b) 458 ft²
Step-by-step explanation:
The total area is the sum of the L-shaped front and back areas and the areas of the 6 rectangular faces.
The front L-shaped area can be considered to be a 12 ft × 12 ft square with a 5 ft × 7 ft rectangle cut from the upper left corner. Its area is then ...
(12 ft)(12 ft) -(5 ft)(7 ft) = (144 -35) ft² = 109 ft² . . . . front area
__
The sum of the areas of the rectangular faces is the product of the width of the figure (5 ft) and the perimeter of the L-shaped face. That perimeter is the sum of the edge lengths. Starting from the lower-left corner and working clockwise, we find the perimeter to be ...
7 ft + 7 ft + 5 ft + 5 ft + 12 ft + 12 ft = 48 ft
Then the sum of rectangular face areas is ...
(48 ft)(5 ft) = 240 ft² . . . . rectangular face area
The total surface area is then ...
2×front area + rectangular face area
= 2×109 ft² +240 ft² = 458 ft² . . . . total surface area
Answer:
W = 69.5 L = 109.5
Step-by-step explanation:
L = 3W-99
Perimeter = 2L + 2W
358 = 2(3W-99) + 2W
358 = 6W-198 + 2W
358 = 8W-198
556 = 8W
69.5 = W
- 358 = 2L+2W
- 358 = 2L + 2(69.5)
- 358 = 2L + 139
- 219 = 2L
- L = 109.5
