Idk im just tryna complete a challenge lol
Answer:
B
Step-by-step explanation:
1. Given mathematical statement

So,

2. Rewrite it as

So,

3. Combine like terms
and 

So,

4. Add
to both sides:

So,

5. Subtract 3 from both sides:

So,

6. Divide both sides by 5:

So,

First distribute 3 to (x-4). that gives you 3x-12. Now your equation is x-2=3x-12. Now you subtract x from 3x. now you're equation is -2=2x-12. then add 12 to the left. You're final answer is 10.
Answer:
≈ 82 feet
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to calculate distance (d)
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Here the hypotenuse is the distance (d) between the 2 poles, hence
d² = 80² + 45² = 6400 + 2025 = 8425 ( take the square root of both sides )
d =
≈ 82 feet ( to the nearest foot )
