Answer:
x = 3
Step-by-step explanation:
According to Euclidian theorem (x+9)^2 = 18*8
(x+9)^2 = 144 find the root for both sides
x + 9 = 12 subtract 9 from both sides
x = 3
-6 +8x = -38
8x = -32
x = -4
I did this by first adding 6 to both sides to get 8x by itself. I then divided by 8 to get x by itself. I remembered to use the - - + rule (Two negatives make a positive, a positive and a negative make a negative). Hope this helps!

Every third term is a sum of previous two.
the sequence 1, 3, 4, 7, 11, 18
You do not have enough information to solve the problem:
The charge was $6.50 without the tip. You need to know the rate that the taxicab charges in order to solve this problem.
For example if the taxicab charged $1.30 per mile then the answer would be $6.50/$1.30 per mile = 5 miles
