Answer:
221
Step-by-step explanation:
use bidmas (brackets,indices, division,multiplication,addition,substraction)
B.6z6
When you multiply with exponents you add the exponents together 4+2=6
Then just multiply the #s 2×3=6
C.
An angle bisector splits angles into halves thus resulting in PNQ. The total angle is however twice the PNQ so 4x + 2.
Hope this helps.
Since 
(density = mass/volume), we can get the mass/weight of the liquid by integrating the density 
over the interior of the tank. This is done with the integral
which is more readily computed in cylindrical coordinates as
26. y= -7/3+ 0 or just y= -7/3
27. y= -10
