No, it isn't a right triangle.
Answer:
A. 1/8
Step-by-step explanation:
m = rise/run
m = (y2-y1)/(x2-x1)
m = (-5- - 4)/(1-9)
m = (-5+4)/(-8)
m = (-1)/(-8)
m = 1/8
Answer: Multiplying 3x and -x we obtain A= -3x^2
I think it’s 74 bc I got it right but your might be different
You just need to plug the values: you have to multiply
and
, and then divide the result by -3.
So, if
, we have 
Which means that 
And the final answer is
