Represent the following phifase as an algebraic expression, where "a number" is the letter \( x \). You do not need to simplify. The cube of the sum of a number and 5 .

To represent "the cube of the sum of a number and 5" as an algebraic expression, start by identifying the sum of the number (represented as \( x \)) and 5, which is \( x + 5 \). Then, take the cube of this sum, which can be expressed as \( (x + 5)^3 \). Now you have the expression \( (x + 5)^3 \) representing the given phrase! It captures both the operation of summation and the cubing, serving as a succinct representation of the original statement.
