Answer 4

To determine which of the given expressions simplifies to the same expression as \( 4x^2 - 3x^2 + 5x - 24 \), we first simplify the original expression:

\[
4x^2 - 3x^2 + 5x - 24 = (4x^2 - 3x^2) + 5x - 24 = 1x^2 + 5x - 24 = x^2 + 5x - 24
\]

Now, we need to check which of the provided options simplifies to \( x^2 + 5x - 24 \).

1. **Option 1: \( 4x(x-6) \)**

\[
4x(x - 6) = 4x^2 - 24x
\]

2. **Option 2: \( (x+6)(x-4) \)**

\[
(x + 6)(x - 4) = x^2 - 4x + 6x - 24 = x^2 + 2x - 24
\]

3. **Option 3: \( (x+8)(x-3) \)**

\[
(x + 8)(x - 3) = x^2 - 3x + 8x - 24 = x^2 + 5x - 24
\]

4. **Option 4: \( 2(x - 12) \)**

\[
2(x - 12) = 2x - 24
\]

From this simplification, we can see that **Option 3: \( (x + 8)(x - 3) \)** simplifies to \( x^2 + 5x - 24 \), which matches the expression we simplified from the original statement.

So, the correct answer is: **(x + 8)(x - 3)**.

Answer 5

To add the polynomial expressions \(5z - 2z^2 - 4z + 5\) and \(6z^2 + 3 - 7z\), we first combine like terms in each expression.

### Step 1: Simplify the first polynomial
Starting with the first polynomial:
\[
5z - 2z^2 - 4z + 5
\]
Combine the like terms \(5z\) and \(-4z\):
\[
(5z - 4z) - 2z^2 + 5 = z - 2z^2 + 5
\]
Rearranging gives:
\[
-2z^2 + z + 5
\]

### Step 2: Rewrite the second polynomial
Now the second polynomial:
\[
6z^2 + 3 - 7z
\]
Rearranging gives:
\[
6z^2 - 7z + 3
\]

### Step 3: Add the two polynomials
Now, add the two simplified polynomials:
\[
(-2z^2 + z + 5) + (6z^2 - 7z + 3)
\]

Combine like terms:
- For \(z^2\): \(-2z^2 + 6z^2 = 4z^2\)
- For \(z\): \(z - 7z = -6z\)
- For the constant: \(5 + 3 = 8\)

Putting it all together, we get:
\[
4z^2 - 6z + 8
\]

### Conclusion
The answer is:
\[
\boxed{4z^2 - 6z + 8}
\]

Answer 6

To simplify the expression \((9x^2 + 17x + 13) - (2x^2 + 12x + 11)\), we can follow these steps:

### Step 1: Distribute the negative sign
Distributing the negative sign to each term in the second polynomial gives:
\[
(9x^2 + 17x + 13) - 2x^2 - 12x - 11
\]

### Step 2: Combine like terms
Now, we can combine the like terms:

1. For the \(x^2\) terms:
\[
9x^2 - 2x^2 = 7x^2
\]

2. For the \(x\) terms:
\[
17x - 12x = 5x
\]

3. For the constant terms:
\[
13 - 11 = 2
\]

### Step 3: Write the result
Putting it all together, we get:
\[
7x^2 + 5x + 2
\]

### Conclusion
Thus, the expression \((9x^2 + 17x + 13) - (2x^2 + 12x + 11)\) simplifies to:
\[
\boxed{7x^2 + 5x + 2}
\]
