Mathematically written:
3 * x + 7 = 25
3x + 7 = 25
3x = 25 - 7
3x = 18
x = 18 / 3
x = 6
Proof:
3 * 6 + 7 = 25
18 + 7 = 25
25 = 25 → both sides of the equation are equal, our answer is correct
Notes:
A number - Is an unknown number, called a variable, which in this case is substituted by the letter x.

Answer:
E, F, A, ED, BC, EF, ABC, EDF
Step-by-step explanation:
The angle and side markings show which segments and angles are congruent.
We can make a table of corresponding pairs based on the number of marks:
marks, angle, side
- A and E, DF and BC
- B and D, ED and AB
- C and F, EF and AC

This can help us fill in the question numbers:
- ∠E is congruent to ∠A
- ∠F is congruent to ∠C
- ∠A is congruent to ∠E
- ED is congruent to AB
- BC is congruent to DF
- EF is congruent to AC
- 8. ΔABC ≅ ΔEDF
