Your answer is 32! 4 divided by 1/8 is 32.
$7, I think. I would not be too sure about it, though.
Answer:
Step-by-step explanation:
6c+31=4c+13
6c - 4c = 13 - 31
2c = -18
c = -9.
D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1
