<u>Answer:</u>

<u>Step-by-step explanation:</u>
We are given the following two points and we are to find the slope of the line which passes through these points:
and 
The formula of the slope is given by:
Slope = 
Substituting the given coordinates in the above formula:
Slope = 
Answer:
32% decrease
Step-by-step explanation:
Solution:
Calculate percentage change
from V1 = 25 to V2 = 17
so:
Hypotenuse of the right triangle: h=sqrt(4^2+6^2)
h=sqrt(16+36)
h=sqrt(52)
h=sqrt(4*13)
h=sqrt(4) sqrt(13)
h=2 sqrt(13)
Total Area: T.A.=2*(4*6/2)+[4+6+2 sqrt(13)] (8)
T.A.=2*(12)+[10+2 sqrt(13)](8)
T.A.=24+(10)(8)+[2 sqrt(13)](8)
T.A.=24+80+16 sqrt(13)
T.A.=104+16 sqrt(13)
Answer:
( 104+16 sqrt(13) )
