Question

• A. $4-\mathrm{x}$
• B. $4÷\mathrm{x}$
• C. $4+\mathrm{x}$
• D. $4\mathrm{x}$

Answer 1

The correct option is D

$4\mathrm{x}$

Justification Of Answer:

Option (A) $4-\mathrm{x}=4-\mathrm{x}$ (constant and variables are never added /subtracted )

Option (B) $4÷\mathrm{x}=\frac{4}{\mathrm{x}}$ (division is a fraction in itself)

Option (C) $4+\mathrm{x}=4+\mathrm{x}$ (constant and variables are never added /subtracted )

Option (D) $4\times \mathrm{x}=4\mathrm{x}$ (multiplication of coefficient with literal gives the product of coefficient followed by the literal)

Thus, Option D is the correct answer
