Square=a^2
trapezoid: a+b over 2 times height
triangle=bxh divide by 2
parallelogram= bxh
its too late but 23.08 so I'm sorry I took so long
Answer:
To find the slope, use the slope formula. The slope formula is Y2-Y1/X2-X1. Plug in any two points into the equation and solve. I will use (6,4) and (9,6).
6-4/9-6
2/3
The slope of the proportional relationship is 2/3.
Hope this helps! :)
Answer:
Scale Factor=2
Step-by-step explanation:
As the rectangle is enlarging from GHIJ to KLMN
then
Sacle Factor = Larger length / Smaller Length
Scale Factor = 5 cm / 2 cm = 2
Scale Factor = 20 cm / 10 cm = 2
Answer:
5 different triangles
Step-by-step explanation:
we know that
The number of diagonals of an n-sided polygon is given by the formula :

where
n is the number of sides
In this problem
n=5
substitute

see the attached figure to better understand the problem
The number of different triangles that can be formed by the sides of the polygon and its diagonals is equal to 5
so
Triangles
AEB
EDC
BCD
ACD
EBC
see the attached figure
