Answer:
<h3>
3x² - 7</h3><h3>The constant value is -7</h3>
Explanation:
Let the unknown number be x.
Three times the square of the number is expressed as;
= 3 * x²
=  3x²
The sum of the resulting expression (3x) and -7 is equivalent to;
= 3x² + (-7)
= 3x² - 7
Hence the mathematical expression of the statement 'the sum of three times the square of the number and -7' is 3x² - 7.
A constant is a value with no variable attached. It  is always standing alone as a number in a an expression. The degree of a constant is zero. According to the resulting expression, the value of the constant in the expression is -7

Answer: The protection of celebrity/ players from the mob is a priority of the sport event management team or company. 
Explanation:
The two strategies that can be implemented to prevent violence by fans:
1. Entry restrictions: Giving access to only limiting crew members, media, and other important staff members near players or any other celebrity/ talent. 
2. Security management during players entry, exit and players interaction with the fans. This is necessary to prevent harm to the players as some people in the crowd are not fans and they can harm players or any other celebrity.
