(6k + 2) - (3k - 2)= 6k + 2 - 3k + 2 = 3k + 4
Let’s try the pythagorean formula.
1) 8^2+15^2=17^2
289=289 Yes
2) 7^2+24^2=26^2
625 ≠ 676 No
3) 6^2+8^2=11^2
100 ≠ 121 No
4) 10^2+24^2=25^2
676 ≠ 625 No
Therefor, 8,15,17 is your answer

Step-by-step explanation:
<u>Step 1: Define</u>
8 - 2(3x - 36) + 4x
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute -2: 8 - 6x + 72 + 4x
- [Addition] Combine like terms (x): -2x + 8 + 72
- [Addition] Combine like terms (Z): -2x + 80
The first thing you should do in these cases is to add the component to component vectors to obtain the resulting vector. In this case all vectors have two components. After finding the resulting vector you must find the module of it by raising each component squared, adding and finding the square root.
I attach the solution.
