Answer:
4√5
Step-by-step explanation:
Let's call it x
According to Euclidean theorem x^2 = 5×16
x^2= 80 and
x = 4√5
There are no real numbers that can do that job.
There's a pair of complex numbers that can do it.
They are
4.5 + i23.23
and
4.5 - i23.23 .
' i ' = the imaginary unit = √(-1)
I think it's along the y-axis.....
Density = m/v
3.86kg=3860g
d= 3860/200
= 19.3g/cm^3
therefore it is gold.
Answer:
-41
Step-by-step explanation:
