Step-by-step explanation:
<u>Perpendicular Bisector</u>
The bisector of a segment defined by points (x1,y1) and (x2,y2) must pass by the midpoint of the segment.
The midpoint (xm,ym) is calculated as follows:
The endpoints of the segment are (-3,-8) and (5,-4), thus the midpoint M is:
Midpoint: M(1,-6)
Let's find the slope of the given segment. The slope can be calculated with the formula:
If the bisector is also perpendicular, its slope m2 and the slope of the segment m1 must comply:
Solving for m2:
Once we have the slope -2 and the point through which our line must pass (1,-6), we compute the equation in its point-slope form:

Answer:
7x - 3
Step-by-step explanation:
3x+(4x-3)
Remove parenthesis
3x + 4x - 3
Combine like terms
3x + 4x = 7x
7x - 3
Answer: 
Step-by-step explanation:
You can use the following formula to calculate the surface area of the right rectangular prism:
Where "w" is the width, "l" is the length, and "h" is the height.
Knowing that this rigth rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.
Then, the surface of the right rectangular prism is:
![SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2](https://tex.z-dn.net/?f=SA%20%3D%202%5B%283cm%2A8cm%29%20%2B%20%288cm%2A5cm%29%20%2B%20%285cm%2A3cm%29%5D%5C%5C%5C%5CSA%3D158cm%5E2)
Answer:

Step-by-step explanation:
Hi there!
To solve this problem, we need to subtract 5:50 from 4:15 pm.
5:50 - 4:15
= 6:00 - 4:15 - 0:10
= 6:00 - 4:00 - 0:10 - 0:15
= 1 hr 35 min
So, your answer would be 1 hr 35 min.
Hope this helps!
