Question

Name the variable that has an even coefficient: 5x, 9v⁴, 12, 18g.

A. 5x
B. 9v⁴
C. 12
D. 18g.

Answer 1

The variable that has an even coefficient among the options given is
`D. 18g`, since 18 is the only even coefficient.

Step-by-step explanation:

The variable that has an even coefficient among the given options
`5x, 9v⁴, 12, 18g`is found by identifying the numerical part (coefficient) that is an even number. An even number is any integer that can be divided evenly by 2 without leaving a remainder.

• 5x - The coefficient here is 5, which is an odd number.
• 9v⁴ - The coefficient is 9, another odd number.
• 12 - This is not a variable, but a constant and its value is even.
• 18g - The coefficient is 18, which is indeed an even number.

So, the correct answer is D. 18g.
