Answer: 
Step-by-step explanation:
Given the following inequality:

You need to solve for "x" in order to find the solution.
The steps are:
1. Add
to both sides of the inequality:

2. Add
to both sides:

3. Divide both sides by
:

Notice that "x" is less than 8. This indicates that 8 is not included in the solution and you must use parentheses.
The solution in Interval notation is:

Answer:
84
Step-by-step explanation:
In interval questions we use LCM
LCM of 7, 12=84
Therefore, the number of beats will pass before he again strikes them at the same time is 84
The answer is 523 because 4,707 divide 9 to be equal numbers for each one I hope it helps
The simplified form would be -4×^2-13x+9
