What is the result of 3x + 4 when x is 4?

What is the result of 3x + 4 when x is 4?

• A. 10
• B. 12
• C. 15
• D. 20

Answer: (D)

To find the result of the expression \(3x + 4\) when \(x\) is equal to 4, start by substituting 4 in place of \(x\) in the expression. So you would have: \[ 3(4) + 4 \] Calculating \(3(4)\) gives you 12. Then, add 4 to this result: \[ 12 + 4 = 16 \] It appears there has been a misunderstanding regarding the calculation in relation to the provided choices. From the calculation, the total we arrive at is 16, which means neither choice provided aligns with the correct outcome. The operation is straightforward: first multiply the coefficient (3) with the value of \(x\) (which is 4), and then simply add 4 to that result. The essential aspect here is applying the order of operations correctly and ensuring all arithmetic operations are performed sequentially and accurately.
