Studdy Solution

STEP 1

Assumptions1. The unknown number is represented by $x$ . "Four less than" means we subtract4 from something3. "Two times" means we multiply something by4. "The cube of a number" means we raise the number to the power of3

STEP 2

First, let's express "the cube of a number" algebraically. As we are using $x$ for the unknown number, the cube of the number will be x^.

STEP 3

Next, let's express "two times the cube of a number". This means we multiply $x^3$ by2. Algebraically, this is expressed as $2x^3$ .

STEP 4

Finally, let's express "four less than two times the cube of a number". This means we subtract4 from $2x^3$ . Algebraically, this is expressed as $2x^3 -4$ .
The equivalent algebraic expression for "four less than two times the cube of a number" is $2x^3 -4$ .
