How to use Distributive Property to solve these problem?8x(10+5)=

How to use Distributive Property to solve these problem? NEED HELP

Actually for this problem you wouldn't even need the distributive property to solve. All you do is add up the 10+5 inside the parenthese and then multiply the result (15) but 8x which will give you an answer of 120x.

But let's say we have this type of question:

10(8x+5).

Here we'll need to distribute because the 8x and 5 can't be added. So what happens is the 10 outside of the parenthese needs to be multiplied in. The way that's done is you multiply every term inside the parenthese by the 10.

10*8x+10*5 = 80x+50.

Two more examples:

7(7y-6) = 7*7y-6*7 = 49y-42

12(3y+8x-6) = 12*3y+12*8x-6*12 = 36y+96x-72

I hope this helped!

A much better explanation than mine. Sadly, math is not my forte. Language and literature is.

Have a good one!

Thank you. My case is the opposite, language and literature are difficult. =]

Greetings Dina!

You asked for assitance with the example you gave "8x(10+5)= n"

I added  the N because it makes it more simpler direction. So let us continue.

8x(10+5)= n

The 8x is a number in of itself. The 10 is multiplied by it. Also, the 5 is multiplied by it.

Let us see it broken down:

10(8x) + 5(8x) = n

Each number in the parentheses is mulitplied by 8x

80x + 40x = n

120x = n

I had to interpolate your question with N in order to show you step by step.

It is similar to to the FOIL method - although you don't use (a+b) (c+d) = y because your only using 8x.

Although I don't recommend wikipedia for much, it explains FOIL pretty well:

Does this help?
