Let's go through each of the questions one by one:

**Question 6 A)** What does 47 represent in the context of the problem?

In the expression \(-16t^2 + 32t + 47\), the term \(47\) represents the initial height of the football when the quarterback throws it from the top of the bleachers.

So, the correct response is: **47 represents the height of the football when the quarterback throws it.**

---

**Question 7 A)** How did Jamie reach her solution?

Jamie started with 50 clients, and each month, her number of clients doubles. The expression \(50 \cdot 2^m\) is used to model this growth. After substituting \(m = 6\):

\[
50 \cdot 2^6 = 50 \cdot 64 = 3200
\]

So, the correct response is: **Jamie substituted m=6 into the expression 50⋅2^6=3200.**

---

**Question 8 A)** Three classmates are substituting \(x = 3\) into their expressions. Let's calculate the results for each classmate:

- **Whitney's expression**: \(4x - 8\)
\[
4(3) - 8 = 12 - 8 = 4
\]

- **Theo's expression**: \(4x^2 - 8\)
\[
4(3^2) - 8 = 4(9) - 8 = 36 - 8 = 28
\]

- **Erin's expression**: \(4x - 8\) (It appears she has the same expression as Whitney)
\[
4(3) - 8 = 12 - 8 = 4
\]

The results are:
- Whitney: 4
- Theo: 28
- Erin: 4

Among the results, **Theo produced the largest value**.

---

**Question 9 A)** In which step did Jenny make a mistake?

Let's review her steps:
- **Step 1**: \(4^5 - 14 \to 1024 - 14\)
- **Step 2**: \(20 - 14 \to 20 - 14\)

The issue is in **Step 1** where Jenny should have correctly calculated \(4^5\) to be \(1024\) instead of moving on to incorrect calculations in subsequent steps.

So the correct response is: **Step 1, Jenny should've multiplied \(4^5\) instead of writing \(5\) as the exponent.**

---

**Question 10 A)** Put the steps in the correct order when multiplying the binomials \((2x - 5)(x + 7)\).

1. Start with the given expression: **(2x - 5)(x + 7)**
2. Expand using the distributive property: **(2x)(x) + (2x)(7) + (-5)(x) + (-5)(7)**
3. Combine like terms: **2x^2 + 14x - 5x - 35**
4. Final simplification: **2x^2 + 9x - 35**

So, the correct order is:
1. (2x - 5)(x + 7)
2. (2x)(x) + (2x)(7) + (-5)(x) + (-5)(7)
3. 2x^2 + 14x - 5x - 35
4. 2x^2 + 9x - 35

If needed, you can now arrange these into final responses as follows:
1. (2x - 5)(x + 7)
2. \( (2x)(x) + (2x)(7) + (-5)(x) + (-5)(7) \)
3. \( 2x^2 + 14x - 5x - 35 \)
4. \( 2x^2 + 9x - 35 \)

Use the Distributive Property to multiply: −3x(4x−5)−3x(4x−5) .(1 point) Responses −12x+15−12x+15negative 12 x plus 15 −12x2+15x−12x2+15xnegative 12 x squared plus 15 x 12x2−15x12x2−15x12 x squared minus 15 x 7x2+8x

To apply the Distributive Property to the expression \(-3x(4x - 5)\), we multiply \(-3x\) by each term inside the parentheses:

1. Multiply \(-3x\) by \(4x\):
\[
-3x \cdot 4x = -12x^2
\]

2. Multiply \(-3x\) by \(-5\):
\[
-3x \cdot -5 = +15x
\]

Now, combine these results:
\[
-12x^2 + 15x
\]

So, the correct response is: **−12x² + 15x** (negative 12 x squared plus 15 x).

Maria is designing a garden for flowers and vegetables. The area of the garden covered by flower beds can be represented by the expression 3x2+5x−23x2+5x−2 square feet. The area of the garden covered by vegetable plants can be represented by the expression 2x2−3x+42x2−3x+4 square feet. What is the total area of both flowers and vegetables combined? x2+x2+ x+x+ square feet

To find the total area of the garden covered by both flowers and vegetables, we need to add the two given expressions for the areas:

1. Area covered by flower beds: \(3x^2 + 5x - 2\)
2. Area covered by vegetable plants: \(2x^2 - 3x + 4\)

Now, we can add these two expressions together:

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

Now, let's combine like terms:

1. Combine the \(x^2\) terms:
\[
3x^2 + 2x^2 = 5x^2
\]

2. Combine the \(x\) terms:
\[
5x - 3x = 2x
\]

3. Combine the constant terms:
\[
-2 + 4 = 2
\]

Now, put it all together:

\[
5x^2 + 2x + 2
\]

Thus, the total area of both flowers and vegetables combined is:

\[
\boxed{5x^2 + 2x + 2} \text{ square feet.}
\]

Alex has a workshop with an area that can be modeled by the expression 4x2+7x−34x2+7x−3 square feet. He agrees to rent out part of his workshop to his friend Matt. Alex agrees to let Matt use a space in his workshop that is 2x2+7x−52x2+7x−5 square feet. What is the expression that models the remainder of Alex's workshop space once he rents Matt his portion? (1 point) Responses 6x2+14x−86x2+14x−8 square feet 6 x squared plus 14 x minus 8 square feet 2x2−82x2−8 square feet 2 x squared minus 8 square feet 2x2+22x2+2 square feet 2 x squared plus 2 square feet 2x2−14x−82x2−14x−8 square feet 2 x squared minus 14 x minus 8 square feet

To find the expression that models the remainder of Alex's workshop space after renting out part of it to Matt, we need to subtract the area that Matt is renting from the total area of the workshop.

1. **Total area of the workshop:**
\[
4x^2 + 7x - 3
\]

2. **Area Matt is renting:**
\[
2x^2 + 7x - 5
\]

Now, we can subtract Matt's area from Alex's total area:

\[
(4x^2 + 7x - 3) - (2x^2 + 7x - 5)
\]

Now, distribute the negative sign across the second expression:

\[
4x^2 + 7x - 3 - 2x^2 - 7x + 5
\]

Next, combine like terms:

1. **Combine the \(x^2\) terms:**
\[
4x^2 - 2x^2 = 2x^2
\]

2. **Combine the \(x\) terms:**
\[
7x - 7x = 0
\]

3. **Combine the constant terms:**
\[
-3 + 5 = 2
\]

Putting it all together:

\[
2x^2 + 0 + 2 = 2x^2 + 2
\]

So, the expression that models the remainder of Alex's workshop space once he rents Matt his portion is:

\[
\boxed{2x^2 + 2} \, \text{square feet.}
\]

When simplified, which expressions produce the trinomial 4x2−20x−244x2−20x−24 ? Select the TWO that apply.(2 points) Responses 4(x2−20x−24)4(x2−20x−24)4 times open paren x squared minus 20 x minus 24 close paren 4(x−6)(x+1)4(x−6)(x+1)4 open paren x minus 6 close paren open paren x plus 1 close paren −4(x2+5x+6)−4(x2+5x+6)negative 4 times open paren x squared plus 5 x plus 6 close paren 4(x2−5x−6)

To determine which expressions simplify to the trinomial \(4x^2 - 20x - 24\), let's analyze the provided options step-by-step:

1. **First Option: \(4(x^2 - 20x - 24)\)**

Distributing \(4\):
\[
4(x^2 - 20x - 24) = 4x^2 - 80x - 96
\]
This does not match \(4x^2 - 20x - 24\).

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

Using the distributive property (FOIL method):
\[
4[(x - 6)(x + 1)] = 4[x^2 + 1x - 6x - 6] = 4[x^2 - 5x - 6]
\]
Distributing \(4\):
\[
4x^2 - 20x - 24
\]
This matches \(4x^2 - 20x - 24\).

3. **Third Option: \(-4(x^2 + 5x + 6)\)**

Distributing \(-4\):
\[
-4(x^2 + 5x + 6) = -4x^2 - 20x - 24
\]
This does not match \(4x^2 - 20x - 24\).

4. **Fourth Option: \(4(x^2 - 5x - 6)\)**

Distributing \(4\):
\[
4(x^2 - 5x - 6) = 4x^2 - 20x - 24
\]
This matches \(4x^2 - 20x - 24\).

Now summarizing the results:

1. **First Option**: \(4(x^2 - 20x - 24)\) - does not match.
2. **Second Option**: \(4(x - 6)(x + 1)\) - matches.
3. **Third Option**: \(-4(x^2 + 5x + 6)\) - does not match.
4. **Fourth Option**: \(4(x^2 - 5x - 6)\) - matches.

Thus, the two options that produce the trinomial \(4x^2 - 20x - 24\) when simplified are:

- **\(4(x - 6)(x + 1)\)**
- **\(4(x^2 - 5x - 6)\)**

So, the correct responses are:
- **\(4(x - 6)(x + 1)\)**
- **\(4(x^2 - 5x - 6)\)**
