I don't understand how to go about this. For an equilateral triangle, you calculate the dot product, but what do you do for an equilateral triangle? How do you do this with the area?

Loading...Does anyone know what is meant by the reference to the problematic limits of integration?
So let me give you a quick example. I'll give you a simple problem that anyone can do in their head, and I'll explain how I'm going to calculate it. The task is: 75-((5*1.05)+(5*8)+(2*7)+(4*2))= Can I calculate like this: 75 (M+) 5*1.05 (M-) 5*8 (M-) 2*7 (M-) 4*2 (M-) Would that give the correct result?…
Hello, I'm in 10th grade at an integrated secondary school with a grammar school upper level, and I chose chemistry as my first core course because I find it interesting. I used to get straight Ds in chemistry in 7th and 8th grade, but since 9th grade, I've only been getting good grades in chemistry,…
Hello, I have two questions about my possible future studies. I don't know what I want to study yet. I have a lazy personality, and I'm really worried that I won't be able to finish my studies because of it. I'm a 18-year-old male, currently in 12th grade, and I'll be taking my Abitur in…
I have a question. I'm currently in the second year of high school. My problem is that my first year report card was disastrous. With an average grade of 2.7 and 2 points in math, I don't know if auditing companies would accept me for a voluntary internship. My grade in economics is in the…

Calculate the sides of the triangle and check whether AC=BC is.
2)
Determine the vectors AB and AC and capture the cross product AB x AC.
A = (1 / 2) * │AB x AC│
Place 35 and convert to z (z = 7).
But how do you calculate (6-z)* 0.5? Is that (3-0.5z)? And how to change if 35=(3-0,5z; 2; -1.5) to come to z=7?
AB x AC = (8│6│0) * (4│3│z)
AB x AC = (6 * z – 0 * 3│0 * 4 – 8 * z│8 * 3 – 6 * 4) = (6 * z│-8 * z│0)
A = (1 / 2) * │(6 * z│-8 * z│0)
A = (1 / 2) * √(6 * z)2 + (8 * z)2 + 02)
A = (1 / 2) * √(100 * z2)
A = (1 / 2) * 10 * z
A = 5 * z
35 = 5 * z
z = 7
