@Will.H Part B pls
OpenStudy (danieldjpon3):
Elevation of D is 6
OpenStudy (3mar):
Part B need to prove that you have got the elevation of city D relative to C one, so if C is below the sea level, accordingly D will be the same. That's it.
OpenStudy (danieldjpon3):
oh ok so is C under sea level?
OpenStudy (danieldjpon3):

Ok ty
OpenStudy (3mar):
You are welcome!
OpenStudy (danieldjpon3):
Is that all for Part B?
OpenStudy (will.h):
Simplify 1/4 * 24 = D
You'd get the answer positive why? Because positive multiplied by positive will be positive. That's all
