Answer:
AB = 18
Step-by-step explanation:
tan 45° = 18/AB
1 = 18/AB
AB = 18

Answer:
D. 0 ≤ x ≤ 8
Step-by-step explanation:
The domain is the set of all possible x-values that will make a function work.
The domain of your graph is [0, 8] or 0 ≤ x ≤ 8.
Answer:
Step-by-step explanation:
The width of the rectangle = x
Therefore the length of the rectangle = 2x, as it is twice its width
We know that the perimeter of a rectangle = 2 × (length + width)
So since the perimeter equals to 30, then we can form the equation:
2×(2x+x) = 30
2×(3x) = 30
6x = 30
x = 5
width of the rectangle = x = 5
length of the rectangle = 2x = 2×5 = 10
If there is an unit which is in the question, remember to add it to the end of the answer. As you have not written any units in the posted question, I will leave it as it is.
Hope this helps :)
