X = 7
5 + x can also be written as 5 + 7
5 + 7 = 12
The answer to this question using the quadratic formula is x= -1+3√5/2 and x=-1-3<span>√5/2
</span>that is a square root, or, 3 times the square root of 5 ALL over 2, except for the 1. Same with the other one.
Each time you are subtracting 1/9 to get the next term
For example, going from term 2 to term 3 is a difference of -1/9
(1 8/9) - (1/9) = 1 7/9
which is why the answer is choice A
Answer:

Step-by-step explanation:
distance between two points:

we have:
(-4, -6), (3, -7)




so we have:

I would say 168 is the answer.
