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.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
it is given that PQ = 2x + 4 and PQ = x. Then the value of PR will be calculated as below:-
PR = PQ + QR
PR = x + 2x + 4
PR = 3x + 4.
Therefore, for the line segment PR, the value of the part PR is equal to 3x + 4.
