Answer:
45 meters
Step-by-step explanation:

S = edge length
Vol = s^3 = 216
There are 6 faces, each has an area of s^2
Answer:
The correct answer is 0 or 5
Step-by-step explanation:
In order to solve this, solve for 0.
2x^2 = 10x
2x^2 - 10x = 0
Now factor the polynomial.
x(2x - 10) = 0
Now set each piece individually equal to 0.
x = 0
2x - 10 = 0
2x = 10
x = 5
<u>Answer:</u>
c = 2.25
<u>Step-by-step explanation:</u>
For the given equation, we can find the value of c by dividing the numerical coefficient of the left-hand side of the equation by 2 and squaring the quotient obtained.

Solving for c to get:

It means that this value of c is added to both sides of the equation.
This equation factored out is (x+20)^2
