Answer:
Length of the final sides: 6 cm and 16 cm
Step-by-step explanation:
The lengths of the sides of the original box are

Later, a piece of tin is cut out from each corner; the piece cut out has the shape of the square: we can call the length of its generic side x. Therefore, the dimensions of the box will now be:

We also know that the area is

And the area can be written as product of length and width, therefore:

So we find:

Solving for x,

Which has two solutions:
x = 13 cm (this is larger than the initial length of the width, therefore we discard it)
x = 2 cm
So, the length of the new sides are

<span>The population of a bacteria culture doubles every 2 minutes. Approximately how many minutes will it take for the population to grow from 1,000 to 500,000 bacteria
</span>
Is not quite that.
min 0 - 1,000
min 2 - 2,000=1,000*2^1
<span>min 4 - 4000=1000*2^2; </span>
min 6 - 8000=1000*2^3
Be careful! It doubles every 2 minutes.
So, 1,000*2^x=500,000
2^x=500. It asks you to approx. You know that 2^9=512, so x=9.
<span>Because the pop doubles every 2 minutes, the result=9*2=18 minutes.
</span>hope it's perfect!
