Step-by-step explanation:
The question in text and on the picture are different.
Going by picture.
When stating the congruence, it is important to stick to right order of vertices.
The first triangle is ΔCBA
<u>Corresponding angles are:</u>
- ∠C ≅ ∠D, ∠B ≅ ∠E, ∠A ≅ ∠ F
<u>Therefore the second triangle is:</u>
X, x+1
x+x+1=131
2x+1=131
2x=131-1=130
x=130÷2 = 65
the integers are 65 and 66
Answer:
Option A.
Step-by-step explanation:
The given equation is
Step 1: Multiply both sides by (x-4).
Step 2: Multiply both sides by 7.
Step 3: Using distributive property.
Step 4: Isolate all terms on one side.
Step 5: Find factors by splitting the middle term.
Step 6: Using zero product property, we get
It means student solved the equation correctly.
Therefore, the correct option is A.
