Answer:
=AC or 7.8102=AC
Step-by-step explanation:
If we connect a line from point A to point C we create a triangle, and we can use pythagorean theorem to find this distance. So the line from point A to point C will be our hypotenuse and the other two distances will be out side lengths.

25+36=
61=
=AC or 7.8102=AC
Answer:
b = -8
Step-by-step explanation:
6b = -42
Divide by 6 on both sides
b = -8
Multiply both sides by 2
(2) 18 = x/2 (2)
the /2 (2) gets canceled out
so it's 36= x
