Answer:
![h = 4\sqrt{3}](https://tex.z-dn.net/?f=h%20%3D%204%5Csqrt%7B3%7D)
Step-by-step explanation:
If the triangle is equilateral, it means that all the sides are the same. Since there are 3 sides in a triangle, each side is 24/3 = 8
Now, in order to find the height, we can use the pythagoeren theroem. Notice that the height bisects(splits the side) into two equal parts, which each part having the length 8/2 = 4
So we have ![h^2 + 4^2 = 8^2](https://tex.z-dn.net/?f=h%5E2%20%2B%204%5E2%20%3D%208%5E2)
![h^2 = 48](https://tex.z-dn.net/?f=h%5E2%20%3D%2048)
![h = 4\sqrt{3}](https://tex.z-dn.net/?f=h%20%3D%204%5Csqrt%7B3%7D)
Answer:
i beleive the correct answer is A.
Step-by-step explanation:
In step 2 she made a mistake of not having a positive sign for 3x because if you multiply -3 and -x that would end up as +3x
