To solve this problem just do the following,
x+9=-12
-9 -9
x=-21
Check
-21+9=-12 = True
Hope this helps!=)
It is critical to open a compass with over half the way in order for the arcs formed to meet for perpendicular bisector.
<h3>What is perpendicular bisector?</h3>
A perpendicular bisector would be a line that cuts a line segment in half and forms a 90-degree angle at the intersection point. In other words, a perpendicular bisector separates a line segment now at midpoint, forming a 90-degree angle.
Now, consider an example;
When you wish to build a perpendicular line on a line segment, like line AB, you do the following;
- Set the compass on a radius more than half the length of the line AB.
- Using A as your center, draw an arc above and below line AB.
- With the same radius and B as our center, draw additional arcs on top or below line AB to join a first arcs on the both side of the line.
- Join the two arc intersections to cut line AB at M.
A line AB appears to be bisected perpendicularly as a result. The arcs would not have met if the compass is opened less than half way down line AB.

Find x
5x-17 = 3x + 1
5x -3x = 17 + 1
2x = 18
2x/2 = 18/2
X = 9
Find the measure of FG
mFG = 5x - 17
mFG = 5(9) - 17
mFG = 45-17
mFG = 28
Answer:
The answer is A, ab<cd.
Step-by-step explanation:
If a, b, c, d are positive, and if a b < c d , then Ab>cd is always true
