Question

Which of the following is a monomial?

• A. $4x$
• B. $a+b+c+d$
• C. $a+b+c$
• D. $a+b$

Answer 1

The correct option is A

$4x$

Determine the monomial.

Explanation for Correct answer

The monomial is an expression with only one term.

Option (A). $4x$

From the given options, the only expression that has a single term is $4x$.

So, option (A) is the correct option.

Explanation for incorrect answer:

Option (B). $a+b+c+d$

The expression $a+b+c+d$ has 4 terms.

So, option (B) is incorrect.

Option (C). $a+b+c$

The expression $a+b+c$ has 3 terms.

So, option (C) is incorrect.

Option (D). $a+b$

And, $a+b$ has 2 terms.

So, option (D) is incorrect.

So, Option (B), Option (C), and Option (D). are incorrect

So, $4x$ is a monomial and the correct option is Option (A)
