Answer:

Step-by-step explanation:
we know that
The volume of a cube is equal to

where
s is the side length of the cube
we have

substitute in the formula


Remember the power rule
----> multiply the exponents
so

f = (f1 f2) / (f1 + f2)
f(f1 + f2) = f1 f2
f f 1 + f f 2 = f1 f 2
f1 f2 - f f2 = f f1
f2 (f1 - f) = f f1
f2 = (f f1) / (f1 - f) <==== solution
Answer:
Step-by-step explanation:
1km=1000 m
1 m=100 cm
1 km=1000×100=100000 cm
27 km=100000×27=2,7 00,000 cms
E: 36 because the total degrees of a parallelogram is 360 and opposite angles of parallelogram’s are equal so the angles diagonal from the given ones are the same. So the corners are 3x, 2x, 3x, 2x. In total that is 10x. 360/10 = 36
