I believe it is x-8=4 if I understand this correctly. Otherwise it's x-4=8.
2x=45-3xs
1. Add 3xs to both sides
2x+3xs=45
2. Factor out the common term X
X(2+3s)=45
3. Divide both sides by 2+3s
X= 45/2+3s
Does this answer your question?
Answer:
B
Step-by-step explanation:
SSS stand for Side Side Side, so the truangle must identify all it's sides. To identify sides it uses lines through the side like in B where 1 side has 1 line, 1 side has 2 lines, and the other side has 3 lines. That is the side identifiers, and because each side in B matches with 1 side in A, means that A and B are congruent because they have the same sides, so SSS.
This is confusing to explain, if you have any questions post them in the comments.
