18 - 3n
3n+18 is an algebraic expression and n is an unknown variable
27
20
The expression is: ab-18
The expression ( 18^{\frac{1}{2}} ) represents the square root of 18. Therefore, the equivalent radical expression is ( \sqrt{18} ), which can also be simplified to ( 3\sqrt{2} ) since ( 18 = 9 \times 2 ).
It is an algebraic expression
The number expression for "18 less than 25" can be written as ( 25 - 18 ). This simplifies to ( 7 ). Thus, the expression represents the value ( 7 ).
There is no equation in the question: only an expression. An expression has no answer.

18 + w
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
As an expression it is: 18-3d
