Which of the binomials below is a factor of this trinomial? x2 – 4x – 12 a. x – 6 b. x – 4 c. x – 2 d. x – 3

The answer is A.) x-6

The middle number is -4 and the last number is -12. Factoring means we want something like

(x+_)(x+_)

So which numbers go in the blanks??

We need two numbers that

- Add together to get -4

-Multiply together to get -12

Try 2 and -6:

2+-6 = -4

2*-6 = -12

This checks out!

Fill in the blanks in

(x+_)(x+_)

with 2 and -6 to get...

(x+2)(x-6)

Which means A is the answer :) Hope this helped you!

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
