Represent the following sentence as an algebraic expression, where "a number" is the letter x. you do not need to simplify. subtracted from the square of a number. 5 is subtracted from the square of a number.

The sentence "5 is subtracted from the square of a number" represented as an algebraic expression is:

Let the number be x.

In this exercise, you're required to write an algebraic expression to represent the word problem (sentence). Also, the number would be denoted by the letter x and no need for further simplification of the algebraic expression.

Translating the word problem (sentence) into an algebraic expression, we have;

Square of a number (x) =

Subtracting 5 from the the square of x, we have;
