Applying the perpendicular bisector theorem, the length of QS is: C. 17 units.
<h3>What is the Perpendicular Bisector Theorem?</h3>
According to the perpendicular bisector theorem, any point on a perpendicular bisector is said to be the same distance from both endpoints of the line form which both were drawn on.
Applying the perpendicular bisector theorem, we have:
3x + 2 = 5x - 8
3x - 5x = -2 - 8
-2x = -10
x = -10/-2
x = 5
QS = 5x - 8 = 5(5) - 8
QS = 17 units

Slope means rise over run method
Answer:Np
Step-by-step explanation:
Part A would be 2 lines below the surface because since he is 2 lines above the surface (represented by +10 feet).
Part B would be -50 feet because he would be BELOW the surface (represented by "-", like -45).
Part C would be 20 because DeWayne would be at the tip of the seaweeds, -20 feet. Since each line is 5 feet, then he would have to swim 20 feet up to reach the surface.
Part D would be 0 feet. Since one line above the surface is 5, and one line below the surface is -5, subtracting or adding 5 would be 0.
