im having a hard time with polynomials it just shows shapes and i dont understand, if somebody could help that would be great :)
Which polynomial does the model represent?
The picture shows a big black square, 2 white rectangles 1 black rectangle 1 little white square and 3 little black squares
A. -x^3 + 2x^2 - 3x + 2
B. x^2 + x - 2
C. -x^2 - x + 2
D. -x^2 + x - 2
Are these answers right? Lemme check I'll be back.
@Herobrine did you ever figure out if they were right?
@LaFyEte is super wrong! I got a 5/21 out of the this!
The answers are C, D, C, B, B, D, C, A, B, A, D, D, C, A, D, D, C, A, A, B, A!
Unless we know the dimensions of the squares and rectangles, how they are arranged, and what the significance of black and white shapes are,
who knows ?
apparently white is + and black is -
big black square: -x^3
small black square: -x
rectangles: x^2 or 1
See what you can do with that...

Rest are essay questions
It's good to see that you have provided your set of answers. However, without the actual questions, it's difficult to assess the accuracy of the answers. Moreover, keep in mind that there could be different versions of the same exam with a different order or number of questions. So, if you could provide the questions as well, it would be more helpful.
To determine which polynomial the model represents, we need to examine the shapes in the picture and their corresponding coefficients.
Let's break down the picture:
- The big black square suggests that there is a term with x^2 (since it is a square shape).
- The two white rectangles imply there are two positive coefficients, potentially representing two terms.
- The one black rectangle implies a negative coefficient, representing one term.
- The little white square and three little black squares suggest there are other terms, possibly with smaller coefficients.
Now, let's analyze the options:
A. -x^3 + 2x^2 - 3x + 2
B. x^2 + x - 2
C. -x^2 - x + 2
D. -x^2 + x - 2
From the picture, we can eliminate options B and D since they don't contain any negative coefficients.
Next, we see that there is no cubed term (x^3) in the picture, so we can eliminate option A.
Finally, we are left with option C:
C. -x^2 - x + 2
This polynomial fits the picture because it has a squared term, a negative coefficient for the black rectangle, and a positive coefficient for the white rectangles.
Therefore, the polynomial that the model represents is option C: -x^2 - x + 2.
