### Example Question #21 : Monomials

Simplify:

**Possible Answers:**

The answers provided do not show the correct simplificaiton.

**Correct answer:**

When multiplying a whole number by a polynomial, we simply multiply that number by whatever coefficient is present in front of the variables of the polynomial. We then maintain the variables in the simplified expression.

### Example Question #22 : Monomials

Simplify the following expression:

**Possible Answers:**

**Correct answer:**

Use the distributive property to multiply the monomial and polynomial.

### Example Question #23 : Monomials

Evaluate the expression:

**Possible Answers:**

**Correct answer:**

Multipying a monomial and trinomial boils down to distributing the monomial amongst all the parts of the trinomial as such:

After some cleanup we get:

### Example Question #24 : Monomials

Multiply:

**Possible Answers:**

**Correct answer:**

All we need to do here is multiply every term within the polynomial by the monomial on the outside of the parentheses: .

To do this we need to multiply every term by and by . Remember that when we multiply by a variable (in this case ), we need to add to each of the exponents.

So this leaves us with .

### Example Question #25 : Monomials

Divide:

**Possible Answers:**

**Correct answer:**

To divide this, we must pull out a common factor from the numerator and denominator.

The common factor from the numerator is only .

The common factor from the denominator is .

The only term that will cancel is the . We cannot cancel the inside and terms because they are different entities of a quantity.

The answer is:

### Example Question #26 : Monomials

Which of the following is equivalent to the given statement?

**Possible Answers:**

**Correct answer:**

Which of the following is equivalent to the given statement?

This question asks us to distribute a monomial through a polynomial. To do so, we need to multiply the monomial (4b) by each part of the polynomial in parentheses.

So our answer in standard form is as follows:

### Example Question #27 : Monomials

Multiply the polynomial by the monomial.

**Possible Answers:**

**Correct answer:**

When multiplying a polynomial and a monomial, distribute the monomial into the polynomial:

Then simplify and the answer is:

### Example Question #28 : Monomials

Multiply the polynomial by the monomial.

**Possible Answers:**

**Correct answer:**

When multiplying a polynomial and a monomial, distribute the monomial into the polynomial:

Then simplify and the answer is:

### Example Question #29 : Monomials

Multiply the polynomial by the monomial.

**Possible Answers:**

**Correct answer:**

When multiplying a polynomial and a monomial, distribute the monomial into the polynomial:

Then simplify and the answer is:

### Example Question #30 : Monomials

Multiply:

**Possible Answers:**

**Correct answer:**
