Explain why you cannot factor the trinomial x(to the power of 2)−12x+6
Answer:
See below
Step-by-step explanation:
You cannot find two whole number integers that give a sum of -12 and a product of 6.
-1 + -11 = -12, but (-1)(-11) = 11, which isn't 6
-2 + -10 = -12, but (-2)(-10) = 20, which isn't 6
...and so on...
x² - 12x + 6
This is in the form of ax² + bx + c.
We can not factorize because b < ac.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
x² - 12x + 6
This is in the form of ax² + bx + c.
Middle-term factorization.
We can not use middle-term factorization because b < ac.
Where a = 1, b = -12 and c = 6
Now,
Using determinant.
x² - 12x + 6
It is in the form of ax² + bx + c
a = 1, b = -12, and x = 6
So,
x = -b ± √(b² - 4ac) / 2a
x = 12 ± √(144 - 24) / 2
x = 12 ± √120 / 2
x = 12 ± 2√30 / 2
x = 6 ± √30
x = 6 + √30 and x = 6 - √30
Thus,
The solutions are x = 6 + √30 and x = 6 - √30.

Answer: To find the area for a parallelogram use the formula A=bh
Step-by-step explanation:
The area of the parallelogram is 32cm.
Since the area of the parallelogram equals base times height, you have to find the base of the parallelogram which, is 8, and then find the height, which is 4.
Then multiply them to get your answer.
Base = 8
Height = 4
8cm x 4cm = 32cm
So, the area of the parallelogram is 32cm.

Find the value of x. Then, classify the triangle (one name for its side lengths, one name for its angles).
20 and acute
ive worked it out on the attachment/picture im not sure if its right but its a guess
Answer:
x = 10
scalene, obtuse
Step-by-step explanation:
Sum of interior angles of a triangle = 180°
⇒ 10x + 8 + 52 + 2x = 180
⇒ 12x + 60 = 180
⇒ 12x = 120
⇒ x = 10
∠A = 52°
∠B = (10 x 10) + 8 = 108°
∠C = 2 x 10 = 20°
Scalene: no equal sides (and no equal angles)
Obtuse: one of the interior angles is bigger than 90°
Oliver has 5 pieces of string that are each 4 2/12 feet long. Destiny has 4 pieces of string that are each 5 14/16 feet long. Use an estimation strategy to determine who has the most string. Choose the name and number to complete the statement. Choose..(Oliver or Destiny) is estimated to have Choose...(1 through 10) more feet of string.
Answer:
Destiny is estimated to have around 4 more feet of string.
Step-by-step explanation:
Oliver:
4 2/12 is rounded to 4.
5x4=20.
Destiny:
5 14/16 is rounded to 6.
4x6=24.
20 is less than 24. So Destiny has more string
24-20=4. Destiny has around 4 more feet of string.
Destiny is estimated to have 4 more feet of string.

C) The distance between the heights of the pelican and heron is -33 feet.
D) The difference in height between the pelican and the trout is -40 feet.
E) The difference in height between the pelican and the trout is 40 feet.
F) The distance between the heights of the pelican and the trout is 40 feet.
Answer:
[A] The difference in height between the pelican and the heron is -33 feet.
[E] The difference in height between the pelican and the trout is 40 feet.
[F] The distance between the heights of the pelican and the trout is 40 feet.
Step-by-step explanation:
Note: 0 the sea level.
Since the heron is perched in a tree 50 feet above sea level and directly below the heron the pelican is flying 17 feet above sea level, you can find the difference in height between the pelican and the heron by subtracting 50 feet from 17 feet.
Then, you get that this is: 17-50= -33 feet
Now, according to the information given in the exercise, you know that the trough is swimming directly below them and its height is 23 feet below sea level. If you represent this with an integer, this is: -23
Therefore you can find the difference in height between the pelican and the trout through the following subtraction:
17-(-23)=17+23=40 feet.
Hence, distance = 40 feet.

what does scholarship mean to you? (must use at least 1 paragraph
I think a scholarship means an opportunity for people to earn an education. Without assistance from an outside source, students may have trouble paying for the degree. Scholarships help students have more time to focus on their studies. For many students, the stresses of working make it difficult for them to graduate on time, or graduate with the high grades they have the potential to achieve. For other students, the work/study life is unsustainable, and they discontinue their studies altogether. And I think scholarships can fill the gap. I feel with the assistance it can support students who fall in the gap between high and low-income levels.
