What is the factored form of this expression?
27t3 – 36t2 – 12+ + 16 =
The factored form of this expression is (9t^2 - 4)(3t - 4)
The polynomial is a function with a degree of 3 and above. Given the polynomial function;
27t^3 – 36t^2 – 12+ + 16 = 0
Group
(27t^3 – 36t^2) – (12t + 16) = 0
Factor out the GCF
9t^2(3t-4)-4(3t-4) = 0

Can someone answer 7-11 for me by 12:00AM
Answer:
Step-by-step explanation:
7). x + y = 4 ⇒ y = 4 - x -----> xy = - 96
x(4 - x) = - 96 ⇔ x² - 4x - 96 = 0
D = ( - 4)² - 4(1)(- 96) = 400 = (20)²
[tex]x_{1}[/tex] = (- ( - 4) - 20) ÷ 2(1) = - 8

Answer:
Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance.Jan 15, 2020shd dhdbxhd shx xhd dhddhdxbxbd hx shs shs xhd dhd zud hx dhd ddbd

10x - 8y =4
-5x + 3y = -9
Please solve with elimination i really need the help!!
please show work
Answer:
x = 6
y = 7
Step-by-step explanation:
Here, (10x - 8y = 4) and (- 5x + 3y = - 9) are two given equation
Now, Name the equation
10x - 8y = 4
take 2 as common we get
2(5x - 4y = 2)
5x - 4y = 2 ...(1)
- 5x + 3y = - 9 ...(2)
Now, Subtract (1) from (2)
5x - 4y = 2
- 5x + 3y = - 9
————————
- y = - 7
y = 7
Now, Put the value of y in equation (1) we get
5x - 4y = 2
5x - 4(7) = 2
5x - 28 = 2
5x = 28 + 2
5x = 30
x = 30÷5
x = 6
Thus, The value of x is 6 and y is 7
FOR VERIFICATION ONLY:
5x - 4y = 2
5(6) - 4(7) = 2
30 - 28 = 2
2 = 2
- 5x + 3y = - 9
- 5(6) + 3(7) = - 9
- 30 + 21 = - 9
- 9 = - 9

Two Tickets to an ice skating performance costs $36. For five tickets it costs $90, and for 9 tickets it costs $162.
The proportional relationship that gives the cost of x tickets is:
[tex]y = 18x[/tex]
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:[tex]y = kx[/tex]
In which k is the constant of proportionality.Two tickets to an ice skating performance costs $36, hence, when [tex]x = 2, y = 36[/tex], then:
[tex]y = kx[/tex]
[tex]36 = 2k[/tex]
[tex]k = \frac{36}{2}[/tex]
[tex]k = 18[/tex]
Hence, the relationship is described by:
[tex]y = 18x[/tex]

Step-by-step explanation:
Anybody Know This. ?
Answer: 4 feet
Step-by-step explanation:
In order to determine the length of side, we need to use what is called the Pythagorean theorem, which states: a² + b² = c² The a and b in this equation are both of the sides of the triangle that we call legs. (I have attached a picture for reference if you do not know what sides I am referring to). The c in this equation refers to the hypotenuse of the triangle. (Again, please refer to the attached photo).
So now, we need to plug in the information we already know into this equation. The height of the ramp will be our a and the distance from the box will be our b. We can see that the hypotenuse (c) is labeled as 5, so we can fill in that information in our equation.
a²+b²=5² (simplify by squaring the 5)
a²+b²=25
Next, we know that the height of the box is 3 feet, which let's us know that our a is 3. Let's plug this new information in.
3²+b²=25 (simplify by squaring the 3)
9+b²=25 (simplify by substracting the 9 from both sides)
25 - 9 = 16b²=16
Hey! Now our equation looks much simpler! Now, all we need to do it square root both of the sides in order to get b by its self.
b²=16
√b² = b
√16 = 4
Final answer: b = 4
I truly hoped this explanation helped! If you feel you still need a bit of help, David May explains the Pythagorean theorem very well in his video titled, "Find The Hypotenuse Using Pythagorean Theorem | Dave May Teaches" if you would like to check it out. Take care! :)
