To work out the LCM, we need their prime factors. So:
2 is simple 2 x 1.
7 is also 7 x 1.
13 is also 13 and 1.
They all have in common "1" - so we keep that aside as 1 figure, rather than 3.
We still have the 2, 7 and 13 leftover.
We then multiply the 1 with the other figures.
So 1 x 2 x 7 x 13 is our answer.
Which is = 182.

Let's remember the equation for the volume of a cube:
V= x^3 where x is the length of one side
Since a cube has equal length for length, width, and height.
Now, use what you're given
V= 1331
And put that in terms of x
x^3 = 1331
Now solve for x!
x= cube root (1331)
Think about it! cube root of 1331 * cube root of 1331 * cube root of 1331... will equal 1331 m^3!
Hope this helps
It will take 20 months for the cost to be same.
Step-by-step explanation:
Apartment A;
Security deposit = $1000
Each month cost = $1200
Let,
x be the number of months.
A(x) = 1000 + 1200x
Apartment B;
Security deposit = $1500
Each month cost = $1175
B(x) = 1500 + 1175x
The cost will be same when the functions are equal, therefore,
A(x) = B(x)
Dividing both sides by 25
It will take 20 months for the cost to be same.

Well first we want to divide 1 by 3 , which is 0.3 , Now we need to divide 4 by 5 which is 0.8 .
We have our answers but 7 needs to be added by their sum so lets put them together by adding them : 0.3 + 0.8 = 1.1.
Now lets add 7 and 1.1 all together , which is 8.1.
