X=8 is the Answer. So the equation would be <span>-8+4(1+5 times 8 )=156 </span>
<span>To figure the amount of tropical fish in the aquarium you multiple length*height*width to find the cubic centimeters of the tank, then divide that number by 10,000. 60*50*30=90,000 cubic centimeters. 90,000/10,000=9. 9 tropical fish could be places in a tank with those dimensions.</span>
Volume of a cylinder is

, where r is the radius and h is the height.
This comes from the area of a circle being

. A cylinder is the area of the base circle multiplied by its height.
Using this formula, the volume of the given cylinder is
i think the answer is x ≤ -8
45.6 would because it is the closer number to the mean (or average) of all the numbers.
