Answer:
The right algebraic expression is 2x - 1
Step-by-step explanation:
Let us change the given phrase from words to mathematics expression
- Twice means multiply by 2
- Less than a number by a given value means the number minus the value
In our question, the phrase is " One less than twice a number "
To change it to an algebraic expression
→ Assume that the number is x
∵ Twice a number means 2 × x = 2x
∵ One less than twice the number means 2x - 1
∴ The algebraic expression is " 2x - 1 "
→ The error in the given expression is
- Translate twice a number to x²
The right algebraic expression is 2x - 1
