Answer:
C
Step-by-step explanation:
The volume of the regular pyramid is 
The base of given pyramid is regular hexagon with side 12 cm. The are of this hexagon consistsof area of 6 equilateral triangles and is equal to

Hence, the volume of the pyramid is

X=34
First add like terms in the equation so that you get the equation 3x-2=100. Next add 2 on both sides so that you then get 3x=102. Lastly divide by 3 on both sides to isolate x. You would then get x=34.
J. -8 is the correct answer



You need a volume of 320000 cm³ of water to fill the water cooler.
X equals 62 because you take 147 and subtract it from 180 and that gives you 33.
then you add 33 and 85 together to give you 118. Then you subtract 118 from 180 and that gives you 62.
x=62
