What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
- The tile along the edge of a triangular community pool needs to be replaced.
- In a right triangle, where the hypotenuse is labelled 8 x² the height is labelled 4 x² + 15, and the base is labelled 8 x + 10
The perimeter will be calculated as:-
P = sum of all the sides
P = 8 x² + 4 x² + 15 + 8 x + 10
P = 12x² + 8x + 25
Therefore the expression represents the total perimeter of the pool edge will be 12x² + 8x + 25
