To construct a perpendicular bisector you set the compass to a span which is greater than half the length of the given line. Then setting the point at one end of the line construct an arc passing through the line . Then repeat this process from the other side of the line keeping the compass at the same setting.
Now draw the perpendicular bisector through the 2 intersections of the arcs. That's it.
Answer:
Jackson should work at least 8 hours this week to achieve his target.
Step-by-step explanation:
Jackson's hourly income = $25
His weekly spending budget = $130
Minimum amount to be pushed to the savings account = $50
So, minimum total amount Jackson should earn this week = 130 + 50 = 180
Number of hours to work this week = 
= 
= 8 rounded to next integer
Hence, Jackson should work at least 8 hours this week to achieve his target.

Answers in the photo.
Solve the equation for r by finding a,b, and c of the quadratic then applying the quadratic formula.
M^3 + 9m =
There is a common factor of m.
= m(m^2 + 9)
That is the complete factorization.
m^2 + 9 is a sum of two squares which is not factorable.
Answer: m(m^2 + 9)
