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
