Answer:
I'm not sure about "11" but 12. is "by the definition of right angles", and 16. is "by the SAS(side angle side) congruency theorem"
The dimensions of the image are twice the dimensions of the preimage,
which indicates that the transformation is a dilation.
- The transformation <em>T</em> is; <u>a dilation transformation with a scale factor of 2, D₂</u>
Reasons:
The transformation applied to ΔABC = T
The image of ΔABC following the transformation, T = ΔA'B'C'
The perimeter of ΔA'B'C' = Twice the perimeter of ΔABC
Therefore, we have;
A'B' + B'C' + A'C' = 2 × (AB + BC + AC)
Which gives
A'B' + B'C' + A'C' = 2·AB + 2·BC + 2·AC
By similar triangles, we have the ratio of corresponding sides as follows;

Which gives;

A'B' = 2·AB
Therefore;
- Triangle ΔA'B'C' is twice the dimension of triangle ΔABC, and <em>T</em> is <u>a dilation transformation with a scale factor of 2, D₂</u>

L= length
W= width
Perimeter= 2L + 2W
substitute the known numbers
34 ft= 2(8 ft) + 2W
34= 16 + 2W
subtract 16 from both sides
18= 2W
divide both sides by 2
9 ft= W
ANSWER: The width is 9 feet.
Hope this helps! :)
Answer:
x= -1/24
Step-by-step explanation:
-5/6x = 20
-5 = 6x × 20
-5 = 120x
-5/120 = x
-1/24 = x
