Answer:
x^3 + 1/x^3 = 488
Step-by-step explanation:
- x^2 + 1/x^2 = 62
- x^2 + 1/x^2 + 2 = 64
- ( adding 2 in both sides )
- (x + 1/x ) ^2 = 64
- x + 1/x = 8
now,
- ( x+ 1/x ) ^ 3 = 512
- x^3 + 1/x^3 + 3 × x × 1/x ( x + 1/x )
- x^3 + 1/x^3 + 3 ( 8 )
- ( since x + 1/x = 8 )
- x^3 + 1/x^3 + 24 = 512
- x^3 + 1/x^3 = 488
hence, we got x^3 + 1/x^3 = 488
Answer: 5 : 4
<u>Step-by-step explanation:</u>
The GCF of 60 and 48 is 12. So, divide both numbers by 12.
60 : 48
<u> ÷12 </u> <u>÷12 </u>
5 : 4
The "n" in this expression will stand for the length of the sides.
Because we know there are 8 sides so 8xn will give us the perimeter.
