2d=22 (add 5 to both sides)
d=11 (divide both sides by 2)
Hope this helps

Question
Which combination of transformations can you use to show that one shape is congruent to another?
A. dilations and reflections
B. reflections and stretches
C. rotations and translations
D. reflections, dilations, and translations
E. rotations, translations, and dilationsANSWER -
ANSWER -
The correct answer to this is:
ROTATIONS AND TRANSLATIONS
Reflection and rotation can also be used but since their both grouped with dilations, they can't be used. When dilation is used, the size of the shape is changed and congruence won't be possible anymore . That's why the answer is the first option.
Answer:
Step-by-step explanation:
8x = -1
x = 
The absolute value lines || means the answer will always be positive, so the final answer is positive 1/8.

Answer:
(b) ... confirm ∠C≅∠E
Step-by-step explanation:
The first step is to read and understand the problem statement. It is asking for a way to prove ΔABC ~ ΔADE by AA similarity. That means you want to show any two of the three ...
For this purpose, lengths of line segments are irrelevant (eliminating the last two answer choices). The fact that ∠A≅∠A is given, so you only need to find an answer choice that will show one of the last two angle congruences.
Obviously, showing ∠B≅∠E (choice A) is not relevant to the problem.
The only answer choice that is relevant to the question is the second one, showing ∠C≅∠E.
