Answer and Step-by-step explanation:

\Huge \boxed{Answer: 7y+33-8n}

Step 1: Expand 7(y+3) :

=7y+21-4(2n-3)

Step 2: Expand -4(2n-3)

=7y+21-8n+12

Step 3: Simplify 7y+33-8n

=7y+33-8n

Answer:

-n+33

Step-by-step explanation:

1. do distributive property

2.  7y+21-8n+12

3. combine like terms

4. 7n and 8n both are like terms so, 7n-8n= -1n or -n

5. 21 and 12 are like terms so, 21+12= 33

answer is:      -n + 33   or    -1n + 33

Answer:

Assuming (6 9) is a fraction I just multipled the coordinates of A,B,C,D by that

Step-by-step explanation:

Example: A coordinates are (-5,-2) so I multiplied -5 by 6/9 which is -10/3, and -2 by 6/9 which is -4/3.

I then plotted (-10/3,-4/3), which would be A'

Do the same for the rest of BCD to find B'C'D'

A person is standing in the middle of a large plaza. The person randomly takes a step either north, south, east or west and then
ivolga24 [154]

Answer:

distance between 2 and 3 away from the origin (0,0)

Step-by-step explanation:

I tried this as a simulation.

Let y = a random number.

for x := 1 to 1000 do begin

for y := 1 to 5 do begin

a := random(4)+1;

if a := 1 then v:= v +1           That is he's going north

if a:=  2 then v:=v - 1           That is south

if a:= 3 then h := h + 1         west

if a :=4 then h :h - 1             east

end;

end;

I am running a thousand simulations  

This not my actual coding. I'm made it so that it runs 5000 times

You don't have to keep score of the distance until the end.

Most of the time it gives me a distance of between 2 and 3. The quadrants are random The horizontal distance and vertical distance come in at 2 and 3 respectively or -2 and 3 or 2 and - 3 or -2 or -3 etc.

Setting this up as a tree would almost give you as many branches as a tree outside your window.  But you can try drawing it you like. At least one of them.

What are the chances of you going straight east on a run

Wouldn't it be 1/4 * 1/4 * 1/4 * 1/4 * 1/4 = 1/1024 = 0.000976

Now imagine the tree branch for this. There are over 1000 branches that it could take.

So five steps going east would be  -1 + -1 + -1 +-1 + - 1 = - 5 = h

Vertical = 0

Running this simulation occasionally does give 0.
