Answer
The meaning of evaluating an algebraic expression means finding the value of the expression for a provided value of the variable. It means an expression value at a particular variable value.
Work Step by Step
Let’s assume an expression:
The distance between a tree and a building is 12x,where,distance is represented by x and consider x as 10cm.
Put the variable value in to the expression.
Therefore, distance between a tree and a building is:
\[\begin{align}
& 12x=12\cdot 10 \\
& =120
\end{align}\]
This means the distance between a tree and a building is 120cm.
