lucas and erick are factoring the polynomial 12x3 – 6x2 8x – 4. lucas groups the polynomial (12x3 8x) (–6x2 – 4) to factor. erick groups the polynomial (12x3 – 6x2) (8x – 4) to factor. who correctly grouped the terms to factor? explain.
Answers
Answer:
Both the students were correct.
Step-by-step explanation:
Given : The polynomial is -
To find : Who correctly grouped the terms to factor.
Lucas group the polynomial -
Now, we solve the Lucas polynomial
Erick group the polynomial -
Now, we solve the Erick polynomial
The factors of Lucas and Erick are same.
Each grouping leads to the same result.
Therefore, Both students are correct.
Answer:
Sample Response: Both students are correct because polynomials can be grouped in different ways to factor. Both ways result in a common binomial factor between the groups. Using the distributive property , this common binomial term can be factored out. Each grouping results in the same two binomial factors.
What did you include in your response? Check all that apply.
Polynomials can be grouped differently to factor.
Each way results in common binomials.
Each can be factored as a product of prime polynomials.

Hi
We need to solve 3x-7=2 for x
Let's start by adding 7 to both sides
3x-7+7=2+7
3x=9
Now just divide both sides by 3 so we can find the value for x
3x/3=9/3
x=3
Now substitute 3 for x in 4x-y=5 so we can find the value for y
4x-7=5
4(3)-y=5
-y+12=5
Add -12
-y+12-12=5-12
-y=-7
Now divide both sides by -1 so we can find the positive value for y
-y/-1=-7/-1
y=7
The answer is A

Answer:
√180 or 5√6
Step-by-step explanation:
Plug in: a^+b^2=c^2
a^2+12^2=18^2
a^2+144=324
subtract 144 from both sides
a=√180
a= 5√6

Below is similar question:
48 out of 100 private buses usually run on time. Out of the buses that are on time, only 36 are owned by Jerry. Out of the remaining 52 buses that usually run late, only 7 are owned by Jerry. What is the probability that a bus is owned by Jerry, given that it runs on time?
A. 0.58
B. 0.67
C. 0.75
D. 0.81
The answer is C as 36/48 = .75
Based on the number of buses owned by Jerry that usually run late, the probability that a bus owned by Jerry would run late is 13.5%.
What is the probability that Jerry's bus would run late?
This can be found as:
= Number of buses that Jerry owns which run late / Total number of buses that run late
Solving gives:
= 7 / 52
= 13.5%
