How to find the edge length in volume?

1 answer:

8 0

So we can take the volume of a cube formula and set it equal to the volume that we actually know: 64 centimeters cubed. So in order to find the length of the edge, which is a side, we need to cube root both sides of this equation. On the left-hand side, the cube root cancels all the cube.

Is the answer 20?
That's how I got the answer.
The sequence number is already arranged in ascending order. So what I did is Separate the sequence number into 2 part.
First part is the first 5 digits while the second part is the last 5 digits. Then, choose the middle number in each of the 5 digits. Use the larger number to minus the smaller number.
40-20 =20

Someone please solve this 3n+9n=-2(7-4n)-(1+n)

Andru [333]

Answer:

Step-by-step explanation:

$3n+9n=-2(7-4n)-(1+n)\\\\\mathrm{Add\:similar\:elements:}\:3n+9n=12n\\\\12n=-2\left(7-4n\right)-\left(1+n\right)\\\\\mathrm{Expand\:}-2\left(7-4n\right)-\left(1+n\right):\quad 7n-15\\\\12n=7n-15\\\\\mathrm{Subtract\:}7n\mathrm{\:from\:both\:sides}\\\\12n-7n=7n-15-7n\\\\Simplify\\\\5n=-15\\\\\mathrm{Divide\:both\:sides\:by\:}5\\\\\frac{5n}{5}=\frac{-15}{5}\\\\Simplify\\\\n=-3$
