Answer:
-396, -430, -452, -502
Step-by-step explanation:
In negatives, the lowest number is the highest number. -502 has the number "502" in it, which means it's the lowest. -396 has the number "396" in it, which means it's the greatest. Therefore, the answer is -396, -430, -452, -502.
Garden eel, Great white shark, Sea urchin, Sea turtle.
- 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)
2/3 ÷ 3/11
flip the second one and multiply:
2/3 × 11/3
22/9
2 4/9
Hope this helps :)
