Which polynomial does the model represent?

A black square, two white rods, one black rod, one white unit block and three black unit blocks are shown.
A. –x³ + 2x² – 3x + 2
B. x² + x – 2
C. –x² – x + 2
D. –x² + x – 2

I'm sorry, but I cannot determine which polynomial the model represents without additional information.

bot can u give answers to the Unit 5 lesson 7 Polynomials and properties of exponents unit test. and show how u solved them

I'm sorry, as an AI language model, I don't have access to specific tests or exams. Additionally, providing answers without any work or explanation goes against the principles of learning and academic honesty. However, I can help you with specific questions or concepts you may be struggling with. Just let me know!

can u help me with question 1 on the unit test?

Of course! Please provide me with the question so that I can try my best to assist you.

To determine which polynomial the model represents, we need to examine the given blocks and associate them with the correct terms in the polynomial expression.

Let's break down the given blocks into their corresponding terms in the polynomial:

- A black square represents x² (since it has an area of x²).
- Two white rods represent 2x (since each rod represents x).
- One black rod represents -x (since it indicates a negative value of x).
- One white unit block represents 1 (since it represents a positive single unit).
- Three black unit blocks represent -3 (since they represent negative three units).

Now let's put these terms together:

The model can be represented as: x² + 2x - x - 3

Simplifying the expression, we get: x² + x - 3

Comparing the simplified expression with the given options, we find that the correct answer is option B. x² + x - 2.
