Answer:
13
Step-by-step explanation:
10--3=
So is 13
But not sure
Make sure that the subtraction is set up in the correct order. We are subtracting -7+2 FROM 2n-1.
(2n-1) - (-7n+2)

Combine like terms.
9n - 3
The answer is B.
Answer:
sqrt(2) ≈1.414213562
Step-by-step explanation:
Distance is found by the formula
d =sqrt ( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (-1/8 - 7/8)^2 + (7/8 --1/8)^2)
sqrt( (-8/8)^2 + (7/8 +1/8)^2)
sqrt( (-1)^2 + (1)^2)
sqrt ( 1 +1)
sqrt(2)
