What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Bob was thinking of a number between 5 and 15 that when squared and added to 23 equals the next number's square.
Now,
Let the value of number = x
Hence, We can formulate;
⇒ x² + 23 = (x + 1)²
Solve for x as;
⇒ x² + 23 = x² + 1 + 2x
⇒ x² - x² + 23 - 1 = 2x
⇒ 22 = 2x
⇒ x = 22/2
⇒ x = 11
Thus, The value of number will be;
⇒ 11
