Final answer:

To double the expressions A) 2x, B) x/2, C) x + 2, and D) x², you multiply each by 2, resulting in 4x, x, 2x + 4, and 2x² respectively.

Step-by-step explanation:

To write an expression that doubles the given mathematical expressions, you need to multiply each expression by 2. Here's how you would double each of the provided options:

  • A) To double 2x, you would write 2(2x) or simply 4x.
  • B) To double x/2, you write 2(x/2), which simplifies to x.
  • C) For x + 2, doubling it would be 2(x + 2) or expanded to 2x + 4.
  • D) Finally, to double x², you would write 2(x²), which remains 2x² after simplification.

It's important to remember that doubling an expression means multiplying the entire expression by 2, which is essentially applying a factor of two to whatever value the original expression holds.
