Answer:

Step-by-step explanation:

Answer:
The length of the three sides 
The triangle <u>is not</u> a right triangle
Step-by-step explanation:
A = (3, 2) , B = ( 6, 9) , C = (10, 6)
Find the lengths using distance formula.




Using Pythagoras theorem :

Longest side is AC . So we will check if it satisfies Pythagoras theorem :

65 ≠ 58 + 25
So the sides does not satisfy Pythagoras theorem. Hence the triangle is not a right triangle.
3(n-8)
You make it so that the three is on the outside of the brakets and that you can FOIL to bring it back to how it used to be

5x(x) + (5x)(4) + (-2)(x) + (-2)(4)=
5x^2 + 20x - 2x - 8=
5x^2 + 18x -8
