Yes, the decimal form of 
is indeed a repeating decimal. The expression is equivalent to 
, which is also 1.3333333 or "1.3 bar", signifying that the 3 will repeat infinitely.
A * b = 21 and b * c = 39. then b is the common factor of the two numbers.
We need to factor these two numbers to know their equivalent values.
21 factors are 1, 3, 7, 21
39 factors are 1, 3, 13, 39
if b = 3, then a = 7 and c = 13.
To check:
a * b = 21 where 7 * 3 = 21 and b * c = 39 where 3 * 13 = 39
We can then conclude the following:
3 is lesser than 7 which is lesser than 13. where b < a < c
OR 13 is greater than 7 which is greater than 3. where c > a > b
not sure if these answers are included in your choices but i hope this helps.
It's 36!!!! hope that helped
14x² - x - 3 = 0
14x² - 7x + 6x - 3 = 0
-7x(-2x + 1) -3(-2x + 1) = 0
(-7x-3) & (-2x+1) = 0
Roots: -7x - 3 = 0
-7x = 3
x = -3/7
OR -2x + 1 = 0
-2x = -1
x = 1/2
In short, Your Roots would be 1/2 and -3/7
Hope this helps!
