Question

-The Greatest Common Factor for the polynomial 12x4y - 16x2y2 + 32y3 is the term 4x2y.
I put FALSE.
-The polynomial 4x2 - 16 is a difference of squares
I put TRUE

Answer 1

@whpalmer4

Answer 2

both are correct

Answer 3

Thank you. I have more.. Do you think you could maybe tell me if I am correct?.. I f not I understand

Answer 4

okay sure

Answer 5

-The polynomial 6xy + 3y - 4x - 2 can be factored into (2x + 1) times ___?___.
I put (3y - 2)
-432, 455, 280, 216, 353, 387, 119, 293, 241, 460, 389, 121, 142
1.Find the mean of the data set.


2.Find the median of the data set.


3.Find the first and third quartiles of the data set.

I put
1. Mean= 299.12


2. Median= 293


3. Q1= 179 Q3= 410.5

Answer 6

@agent0smith

Answer 7

all are correct
the mean value with me is 299.07 soo i think it wouldnt make a great difference
good job

Answer 8

I'd recommend posting one question at a time - especially when they're completely unrelated ( like factoring and then statistics)

Answer 9

okay thank you.
So I only have one that I need help on...
Do you think you could help me? Then I have more answers to check. I'm sorry for so many, but I really want to make an A in this class and have a 89% so.

The one I need help with is:
Factor the polynomial 6x2 + 7x - 20. Which one of the following is a factor?
Answer choices:
3x - 4)
(x - 2)
(2x - 1)
(2x + 1)

Answer 10

Okay. Sorry about that..

Answer 11

\[\large 6x^2 + 7x - 20\]Factor it by grouping -

First you need to multiply the 6 by the -20, which gives -120

Now find two numbers that will multiply to -120, and add up to the middle number, +7

Answer 12

uhm...
-8 and +15

Answer 13

Yep, so now you use those two numbers to break up that middle 7x into 15x - 8x:
\[\large 6x^2 + 15x - 8x - 20\]now try factoring by grouping (there's a common factor in the first two terms, and a common factor in the last two)

Answer 14

3x(2x+5)
-4(2x+5)

Answer 15

So the answer is (3x-4) correct?

Answer 16

Yes
