Answer:
Solutions:-5,0,9,6
Not solutions: 12.5,10
Explanation:
The inequality that was given is:
20 > 5 + 3x
First, group similar terms;
20 - 5 < 3x
15 < 3x
x = 5
Thus, the solutions are:-3.5, 5, 4 3/4, -15
The not solutions are:-10 2/3, 129,
Hope this helps! :)
I think it’s D or maybe just maybe it’s will have to be B
The area of the poster is 216 inches.
The formula for the area of a parallelogram is a=bh (area=base•height).
so a = 12 • 18
a = 216 inches
The answer is: 
The explanation for this answer is shown below:
1. By definition, the amount of second required for the pendulum to move from its resting position and return, is the period.
2. As you can see in the graph attached in the exercise, the wave interval is repeating every two units of x (or
).
3. Therefore, the period is
.
