Answer:
this is ez
Step-by-step explanation:
2.5 g converted to kg: 2.5 g x 1 kg/1000 g = 0.0025 kg = 2.5x10-3 kg
cm3 converted to m3: 1 cm3 x 10-6 m3/cm3 = 1x10-6 m3
Thus, the conversion of 2.5 g/cm3 to kg/m3 would be 2.5x10-3 kg/10-6 m3 = 2.5x103 kg/m3 = 2500 kg/m3
If the 3 is supposed to be replaced by any x's, then the answer would be 29 I believe.
There is nothing here for anyone to work off, If you have a picture or screenshot that would be very nice!
To calculate minimum value, do -b/2a to get the x-value, and plug it in to get the y-value:
-6/8 = -3/4

So the minimum value of g(x) is -81/4
This shows that g(x) has a lesser minimum value than f(x)
