<h3>The volume of cube is 729 cubic centimeter</h3>
<em><u>Solution:</u></em>
<em><u>The surface area of cube is given as:</u></em>

Where, "a" is the length of side of cube
Given that, surface area = 486 square centimeter

<u><em>Find the volume of cube:</em></u>

Thus volume of cube is 729 cubic centimeter
A. The term "units" refers to the measurements in the original question or problem. When looking at the question, the units we are measuring are dollars/feet.
B. In this case, the f'(x) means we are looking for the cost (in dollars) to drill the next foot down.
C. Since the cost increases the more feet we drill down, the sign of f'(x) is positive.
(2x +3)(2x-3)= 0
x= -3/2 x = 3/2
Answer:
(x,y) = (0,0)
Step-by-step explanation:
Let both as equation (1) and (2)
put equal both sides -x = -7x
-x + 7x = 0
6x = 0
x = 0
put it in 2nd equation
y = -7(0)
y = 0
