The algebra tiles shows the polynomial x² - 2x - 8
<h3>
Polynomial</h3>
Polynomial is an expression that involves only the operations of <em>addition, subtraction, multiplication</em> of variables.
Algebra tiles are square and rectangle shaped tiles or tiles that represent numbers and variables.
From the image:
Polynomial = x² + x + x - x - x - x - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 = x² - 2x - 8
The algebra tiles shows the polynomial x² - 2x - 8

Answer:
Step-by-step explanation:
You have 3 points and need to find ax2 + bx + c = y. First use (0,2). x is zero, so y = 2 = c. You have c. Now put (-1,0) into the equation. 0 = 1a -b + 2. Rearrange so you get b = a + 2. Now use the other point. a*(-2 squared) + b*(-2) + 2 = 0. Simplify and substitute (a + 2) for b and you will have the answer.
Answer:
277,200
Step-by-step explanation:
To find the number of permutation we can form from the letters of the word "engineering", we first need to find the frequencies of the different letters present.
E = 3
G = 2
N= 3
I = 2
R = 1
Now that we have the frequencies, we count the number of letters in the word "engineering".
E N G I N E E R I N G
11 letters
Now we take the factorial of total number of letters and divide it by the number of repeats and their factorial
So we get:
We remove the 1! because it will just yield 1.
So the total number of permutations from the letters of the word "engineering" will be:
Total number of permutations = 
Total number of permutations = 277,200

It completely depends on the teacher, but typically exams seem to be worth at least 50% of your final grade.
