slope = rise over run = y/x
A (-1,3) slope = 3/-1 = -3
B (1,2) slope = 2/1 = 2
C (-3,-1) slope = -1/-3 = 1/3
2 lines need to be negative reciprocals in order to be a right triangle
negative reciprocal of -3 is 1/3
so this is a right triangle
It’s simple, do: 8+8+10+10, just add them you will get 36. The explanation is: Perimeter is add up all the sides, since it is a rectangle it has congruent sides, so they have the same length
Answer:
B) 25
Step-by-step explanation:
First, you add up all the numbers. Then, you divide it by 9 which is the total amount of numbers there are.
(2x^3-6x-4)/x if your simplifying that's the answer
I believe the answer is b
