Write an expression to the representative the sum of three times the square of the number and -7 In your expression, what is the value of the constant

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

i literally just read the book and studied it for months so i could you, but i need to know where these questions are coming from. they are too general.
