Question

Combine like terms and classify the polynomial by the number of terms.

Answer 1

Answer:

(B) Monomial

Step-by-step explanation:

The given polynomial is:

$7x+3x-x$

Upon solving the above p[polynomial by combining the like terms, we have

=$10x-x$

=$9x$

Now, A monomial is an algebraic expression consisting of one term., therefore by the definition of monomial, the above given polynomial is a monomial.

Therefore, option (B) is correct.

Answer 2

The answer is B. monomial.

7x + 3x - x = 10x - x = 9x

There is only one term (9x), so the polynomial is actually monomial (mono- = one)
