The answer is B due to the corresponding 130
(20+40)+4
So basically the easiest way to remember is for example:
Normal: 69+45
Distributive property: (60+40)+9+5
———————————————————
So if you have 24 you need to distribute the numbers to make them into tens. That’s how you get 4.

I didn’t explain it very well but hope it helped a little bit.
You must do to the left hand side what you do to the right hand side.
We just want to get only A on the LHS and how much A is on the RHS.
A + 24 - 24 = -15 - 24 // we get rid of the +24 to only leave A and we do it on the other side because we always do that
A = -39
Answer:
I think is it first one. If it wrong I am so sorry ;w; Good Luck :3
So here is the solution of the given problem above.
To find the area we are just going to use this formula. A = L x W.
Let x be the width and 2x is the length. Given that the area is 8 square meters. So let us find x first.
Plug in the values:
8 = (2x)(x)
8 = 2x^2 << divide both sides by 2 and we get
4 = x^2
Then square 4 and x^ 2 and we got
2 = x
Therefore, the width of the room is 2 meters and the length 2x is 4 meters. Hope this is the answer that you are looking for.
