To rewrite the polynomial \((x + 8)(x - 2)\) using the Distributive Property, we will multiply each term in the first binomial by each term in the second binomial.

1. Multiply \(x\) by \(x\):
\[
x \cdot x = x^2
\]

2. Multiply \(x\) by \(-2\):
\[
x \cdot (-2) = -2x
\]

3. Multiply \(8\) by \(x\):
\[
8 \cdot x = 8x
\]

4. Multiply \(8\) by \(-2\):
\[
8 \cdot (-2) = -16
\]

Now, combine all the results:
\[
x^2 - 2x + 8x - 16
\]

Combine the like terms \(-2x\) and \(8x\):
\[
x^2 + 6x - 16
\]

So, using the Distributive Property, the polynomial \((x + 8)(x - 2)\) can be rewritten as:
\[
x^2 + 6x - 16
\]

Thus, filling in the blanks:
\[
(1)x^2 + (6)x + (-16)
\]

To rewrite the expression \(3x(x + 3)\) using the Distributive Property, you multiply \(3x\) by each term inside the parentheses.

1. Multiply \(3x\) by \(x\):
\[
3x \cdot x = 3x^2
\]

2. Multiply \(3x\) by \(3\):
\[
3x \cdot 3 = 9x
\]

Now, combine the results:
\[
3x(x + 3) = 3x^2 + 9x
\]

Thus, the expression rewritten using the Distributive Property is:
\[
3x^2 + 9x
\]

To find the product of the polynomials \((2x + 1)(x - 4)\) using the Distributive Property, we will multiply each term in the first polynomial by each term in the second polynomial.

1. Multiply \(2x\) by \(x\):
\[
2x \cdot x = 2x^2
\]

2. Multiply \(2x\) by \(-4\):
\[
2x \cdot (-4) = -8x
\]

3. Multiply \(1\) by \(x\):
\[
1 \cdot x = x
\]

4. Multiply \(1\) by \(-4\):
\[
1 \cdot (-4) = -4
\]

Now, combine all the results:
\[
2x^2 - 8x + x - 4
\]

Next, combine the like terms \(-8x\) and \(x\):
\[
2x^2 - 7x - 4
\]

So, the product of the polynomials \((2x + 1)(x - 4)\) can be rewritten as:
\[
2x^2 + (-7)x + (-4)
\]

Thus, filling in the blanks:
\[
(2)x^2 + (-7)x + (-4)
\]

To prove that Expression A \((x+4)(x−2)\) is equivalent to Expression B \(x^2+2x−8\), we can follow these steps using the distributive property.

1. **First:** Start with the original expression.
- Option #1: \((x+4)(x−2)\)

2. **Second:** Apply the distributive property (also known as the FOIL method for binomials) to expand the expression.
- Option #4: \(x(x)−x(2)+4(x)−4(2)\)

3. **Third:** Combine the like terms to simplify the expression.
- Option #2: \(x^2−2x+4x−8\)

4. **Fourth:** Write the final simplified expression.
- Option #3: \(x^2+2x−8\)

Putting it all together:

- **First:** Option # (1)
- **Second:** Option # (4)
- **Third:** Option # (2)
- **Fourth:** Option # (3)

To identify two expressions that will be equivalent to \(2x^2 - 8x - 10\) when distributed, we can test each option by distributing and simplifying.

1. **Option #1:** \(2x(x - 4x - 5)\)
- Distribute: \(2x(x) - 2x(4x) - 2x(5) = 2x^2 - 8x - 10\) (This simplifies to the original expression.)

2. **Option #2:** \((2x + 2)(x - 5)\)
- Distribute: \((2x)(x) + (2)(x) + (2x)(-5) + (2)(-5) = 2x^2 + 2x - 10x - 10 = 2x^2 - 8x - 10\) (This simplifies to the original expression.)

3. **Option #3:** \(2x(x - 5) + 2(x - 5)\)
- Distribute \(2x(x - 5) \rightarrow 2x^2 - 10x\)
- Distribute \(2(x - 5) \rightarrow 2x - 10\)
- Combine: \(2x^2 - 10x + 2x - 10 = 2x^2 - 8x - 10\) (This simplifies to the original expression.)

4. **Option #4:** \((x - 5)(x - 3)\)
- Distribute: \(x^2 - 3x - 5x + 15 = x^2 - 8x + 15\) (This is not equivalent.)

5. **Option #5:** \(-6x - 10\)
- This is not equivalent; it doesn't contain the \(2x^2\) term.

**Conclusion:**
The expressions that are equivalent to \(2x^2 - 8x - 10\) when distributed are:

- **Option #1:** \(2x(x - 4x - 5)\)
- **Option #2:** \((2x + 2)(x - 5)\)

So, the answer is:
- **Option # (1)** and **Option # (2)**.
