7 n. 87 in 154 in

Not Possible

Step-by-step explanation:

This uses what is known as the triangle inequality.  Basically if you add two sides the sum will be greater than the third, then if you subtract two sides  it will be less than the third, keeping in mind to subtract the smaller one from the larger one.

Your sides are 7, 87 and 154

Now, I could go through each and every combination, but right away I can see 87 + 7 is less than 154, so this is not a valid triangle.  

Similarly 154-7 is greater than 87 AND 154 - 87 is greater than 7, so btoh of these also mean it is not a valid triangle.  

If you it doesn't make sense how I got to this conclusion I can explain.  

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
