Answer:
scalene
Step-by-step explanation:
The answer of this question is C. Because the different on y value is increasing by 2 so it’s linear
Answer:
a = 7
Step-by-step explanation:
Using the rule of radicals

+ (

= 3 + 4
= 7 → in the form a
with a = 7
- I’m assuming the expression implies the following:
(1-n)/(n^2 - 1)
The steps goes as follows:
= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)
At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.
= -1/(n+1) , which is the answer
Note: You could also see it as 1/-(n+1) or 1/(-n-1)
Answer:
-9
Step-by-step explanation:
