Factorial is the correct answer because in combinations the order does not matter
Answer;
C) The second arc should be centered at C.
Explanation;
Assuming the goal is to construct a line parallel to AB that passes through given point C.
-Draw a line through C and across AB at an angle creating D.
- With the compass width about half of DC, and center D, draw the first arc to cross both lines.
-Using the same compass width , draw the second arc with center C.
-Then set the compass width to the lower arc (the first arc)
- Move the compass to the second arc. Mark off an arc to make point E
-Draw a straight line through C and E
Thus the line CE will be parallel to line AB
The answer is x=-80.
First subtract 4 from both sides.
-6=
+4
-6-4=+4-4
-10=
Multiply 8 on both sides to isolate x.
-10·8=
-80=x
