Answer:
Step-by-step explanation:
Using the given information, we have ...
BH = 2·HF
3x +6 = 2(2x -1)
3x +6 = 4x -2
8 = x
__
The length of the median is ...
BF = BH + HF
BF = (3x +6) +(2x -1) = 5x +5
BF = 5·8 +5
BF = 45
Answer:
3

9 - 3,3
the common factor is three (its what they have in common)
Answer:
The formula A=12bh is used to find the area of the top and bases triangular faces, A= area, b= base, and h= height. The formula A=lw is used to find the area of the three retangular side faces, A= area, l= lenght, and w= width
Step-by-step explanation:
Answer: 1,2,3, and 5
Step-by-step explanation:
The isometries that preserve a shapes angles and line segments making the pre image congruent to the (post) image are :
Reflections, rotations, translations
These are rigid transformations. Think of your ruler. If you flip it, slide it, or rotate it around, did the ruler change shape? No. Just positions.
If you dilate something, you are either making it larger or smaller, therefore changing the size of the shape.
Anything that has dilation in its transformation does not have congruent shapes.
