2(5x^2+2x)+2(3x^2)
10x^2+4x+6x^2
16x^2+4x
D is the correct answer.
POH is the -log [ OH- ]. Using this equation, simply find the -log of the OH- concentration to find the pOH:
pOH = - log ( 0.000086 ) = 4.07
This is Pythagorean theorem, a^2+b^2=c^2 , a = 33 and c = 37 so b^2 + 1089 = 1369 , b^2 = 280 , b = 16.73m
