Which of the following quadratics has 2x − 3 as a factor?
Answers
Explain why you cannot factor the trinomial x(to the power of 2)−12x+6
Answers
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.

Ayanna plans to bake 3 types of cookies to take to a party. She needs to be sure that she has enough flour. The chocolate cookies use
1 3/4
cups of flour, the sugar cookies use
3 2/3
cups of flour, and the oatmeal spice cookies require
1 7/8
cups of flour. Which is the BEST estimate of the total amount of flour she will need?
Answers
They have enough flour for
414÷34===174×43173523
batches and they have enough butter for
112÷13===32×3192412
batches, so the butter is the limiting factor. Thus, they can make 4 whole batches of a dozen cookies each.

B) The difference in height between the pelican and the heron is 33 feet.
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.
Answers
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.

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°

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.
