Distributive property: a(b + c) = ab + ac

4n - 2 - 2n = 2(2n - 1 - n)

4n - 2 - 2n = 2n - 2 = 2(n - 1)

How to check that a number is divisible by 3 or not?? Need a best shortcut!!
Lilit [14]
If your number is quite large, like 3 digit or higher than that, then calculate the sum of their digits, if they will be divisible by 3, then the number is divisible, otherwise not.

For example. - "11055" 
Here, sum of digits = 1 + 1 + 0 + 5 + 5 = 12
As 12/3 = 4 (Divisible)

In short, This number would be divisible.

Hope this helps!

Factor:<br> 40a^2 - 32a<br><br> For those who don’t know ^2 means squared or to the power of two
olga55 [171]

Answer:

8a(5a - 4)

Step-by-step explanation:

To factor this expression, see what numbers and variables these two terms have in common. I can see that they both have the variable a, so a can be factored out.

40 and -32 also have 8 in common, because they are both cleanly divisible by 8.

Now we can factor 8a out of 40a^2 - 32a. Think of how many times 8a goes into 40a^2 and -32a.

8a(5a - 4)
