Answer:
(0, 24]
Step-by-step explanation:
The horizontal extent of the graph is from 0 to 24. There is an open circle at x=0, and a closed circle at x=24. Hence, the domain of the function is ...
0 < x ≤ 24
In interval notation, this is
(0, 24]

Answer:
Step-by-step explanation:
Since the figure is a square, the area is (1/3)^2 or 1/3 x 1/3

7.5%
Step-by-step explanation:
86 - 80 / 80 = 0.075
so 7.5%
Answer:
207 m²
Step-by-step explanation:
width = x
length = 3x - 4
2(length + width ) = Perimeter
2(3x - 4 + x) = 64
4x - 4 = 64/2
4x - 4 = 32
4x = 32 + 4
4x = 36
x = 9 m - width
length = 3x - 4 = 3 · 9 - 4 = 23 m
Area = length · width = 23 · 9 = 207 m²
