A segment is only a "midsegment" if it connects midpoints. When labels above and below are 9 and 72, it is clearly not a midsegment. However, because it is parallel to the base, segments above and below on one side are proportional to those in similar positions on the other side.
72/9 = 56/(3x -20)
We can multiply by (3x -20)/8 to get
3x -20 = 7
3x = 27
x = 9
0=41

Question:
Select expression that is mathematically equivalent to

a) 
b) 
c) 
d) 
Answer:

Step-by-step explanation:
Given

Required
Determine its equivalent
Start by writing y - z in bracket;

becomes

When - is used as divide, it is equivalent to /
The given expression can then be rewritten as

Hence;
<em />
<em> is equivalent to </em>
<em />
Answer:
B
Step-by-step explanation:
The slope of graph b is -3/2
Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
Suppose the base of right triangle sail is b
Suppose the height of right triangle sail is h
It is given that, it is three times higher as it is wide.

Area of right triangle is A = 

Plugging the value of h in terms of b



Hence height h = 
Hecne the height of sail is 6 meters. : Answer
Hope it will help :)
