Answer:

x=1 or x=1/2

Step-by-step explanation:

9x^2 - 12x +3

9x^2 -(9+3)x+3

9x^2-9x-3x+3

9x(x-1)-3(x-1)

(x-1)(9x-3)

so,

either x-1=0

x=1

or

9x-3=0

9x=3

x=3/9

x=1/2

6 numbers form an arithmetic sequence with a common difference of 4. THe sum of these numbers equals 12. What are the 6 numbers.
frutty [35]

Answer: See explanation

Step-by-step explanation:

We will use the formula for an arithmetic sequence which will be:

a + (n - 1)d

where a = unknown

n = 6

d = 4

We then slot them into the formula

a + (6 - 1)4 = 12

a + 5(4) = 12

a + 20 = 12

a = 12 - 20

a = -8

The 6 numbers are

1st term = -8

2nd term = -8 + 4 = -4

3rd term = -4 + 4 = 0

4th term = 0 + 4 = 4

5th term = 4 + 4 = 8

6th term = 8 + 4 = 12
