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:
-3
Step-by-step explanation:
2a - 6 = 4a
subtract 2a giving you -6 = 2a
divide by 2 from both sides so that a will be by itself
giving you -6 ÷ 2 = a
-6 ÷ 2 = -3
so a = -3
Answer:
Its right
Step-by-step explanation:
Answer:
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. ... When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.
Answer:
The points A , B and C lie on the line m . They are collinear.
The points D , B and E lie on the line n . They are collinear.
There is no line that goes through all three points A , B and D . So, they are not collinear.
