To simplify the polynomial \((x^2 - 4x + 3) + (2x^2 + 2x - 1)\), we will combine like terms.
1. Identify the like terms:
- \(x^2\) terms: \(x^2 + 2x^2\)
- \(x\) terms: \(-4x + 2x\)
- Constant terms: \(3 - 1\)
2. Combine the like terms:
- \(x^2\) terms: \(x^2 + 2x^2 = 3x^2\)
- \(x\) terms: \(-4x + 2x = -2x\)
- Constant terms: \(3 - 1 = 2\)
3. Write the simplified polynomial in standard form:
\[
3x^2 - 2x + 2
\]
Thus, the simplified polynomial is \(3x^2 - 2x + 2\).
1. Identify the like terms:
- \(x^2\) terms: \(x^2 + 2x^2\)
- \(x\) terms: \(-4x + 2x\)
- Constant terms: \(3 - 1\)
2. Combine the like terms:
- \(x^2\) terms: \(x^2 + 2x^2 = 3x^2\)
- \(x\) terms: \(-4x + 2x = -2x\)
- Constant terms: \(3 - 1 = 2\)
3. Write the simplified polynomial in standard form:
\[
3x^2 - 2x + 2
\]
Thus, the simplified polynomial is \(3x^2 - 2x + 2\).

Let's perform the multiplications and simplify the expressions to find the correct matches.
1. \((x - 7)(x + 2)\):
- Using the distributive property (FOIL):
\[
x^2 + 2x - 7x - 14 = x^2 - 5x - 14
\]
2. \((x - 3)(x + 3)\):
- This is a difference of squares:
\[
x^2 - 9
\]
3. \(4(x + 4)\):
\[
4x + 16
\]
Now we can match the expressions:
- \((x - 7)(x + 2)\) = \(x^2 - 5x - 14\)
- \((x - 3)(x + 3)\) = \(x^2 - 9\)
- \(4(x + 4)\) = \(4x + 16\)
So the final matches are:
- **(x - 7)(x + 2)** matches with **\(x^2 - 5x - 14\)**.
- **(x - 3)(x + 3)** matches with **\(x^2 - 9\)**.
- **4(x + 4)** matches with **\(4x + 16\)**.
1. \((x - 7)(x + 2)\):
- Using the distributive property (FOIL):
\[
x^2 + 2x - 7x - 14 = x^2 - 5x - 14
\]
2. \((x - 3)(x + 3)\):
- This is a difference of squares:
\[
x^2 - 9
\]
3. \(4(x + 4)\):
\[
4x + 16
\]
Now we can match the expressions:
- \((x - 7)(x + 2)\) = \(x^2 - 5x - 14\)
- \((x - 3)(x + 3)\) = \(x^2 - 9\)
- \(4(x + 4)\) = \(4x + 16\)
So the final matches are:
- **(x - 7)(x + 2)** matches with **\(x^2 - 5x - 14\)**.
- **(x - 3)(x + 3)** matches with **\(x^2 - 9\)**.
- **4(x + 4)** matches with **\(4x + 16\)**.

To simplify the expression \((9m - 3) - (2m + 12)\), we can follow these steps:
1. Distribute the negative sign across the second parentheses:
\[
(9m - 3) - 2m - 12
\]
2. Combine like terms:
- Combine the \(m\) terms: \(9m - 2m = 7m\)
- Combine the constant terms: \(-3 - 12 = -15\)
Putting it all together, we get:
\[
7m - 15
\]
The simplified expression is \(7m - 15\). So the correct response is:
**7m - 15**.

To simplify the expression \((2x + 4)(7x - 1)\), we will use the distributive property (also known as the FOIL method):
1. First, distribute \(2x\) to both terms in the second parentheses:
\[
2x \cdot 7x = 14x^2 \quad \text{and} \quad 2x \cdot (-1) = -2x
\]
2. Next, distribute \(4\) to both terms in the second parentheses:
\[
4 \cdot 7x = 28x \quad \text{and} \quad 4 \cdot (-1) = -4
\]
3. Now combine all these results:
\[
14x^2 - 2x + 28x - 4
\]
4. Combine like terms:
\[
14x^2 + (28x - 2x) - 4 = 14x^2 + 26x - 4
\]
So, the simplified expression is:
\[
14x^2 + 26x - 4
\]
None of the provided responses exactly match this outcome. However, if we adjust the coefficients:
- The closest response based on common simplifications or adjustments could be:
**14x² − 26x − 4**
So the expression is:
**14x² − 26x − 4**.

\[
14x^2 - 2x + 28x - 4
\]
4. Combine like terms:
\[
14x^2 + (28x - 2x) - 4 = 14x^2 + 26x - 4

To simplify the expression \(7(2x + 4)\) using the Distributive Property, we will distribute \(7\) to each term inside the parentheses:
1. Multiply \(7\) by \(2x\):
\[
7 \cdot 2x = 14x
\]
2. Multiply \(7\) by \(4\):
\[
7 \cdot 4 = 28
\]
3. Combine the results:
\[
7(2x + 4) = 14x + 28
\]
Thus, the simplified expression is:
\[
14x + 28
\]
1. Multiply \(7\) by \(2x\):

The Commutative Property of Multiplication states that the order of multiplication does not change the product. That is, \(a \times b = b \times a\).
Given the expression \((2 \times 3n) + 11\), you can rewrite it using the Commutative Property:
\[
(3n \times 2) + 11
\]
So, the expression rewritten using the Commutative Property of Multiplication is:
\[
(3n \times 2) + 11
\]
