The perimeter is 30 units
Answer:
Step-by-step explanation:
Use formula
where
= new score
= old score
= the mean
= standard deviation
In your case,
Hence,
So,
Ok so
-5x = 30
First divide both sides by -5 to get x by itself
You get: x = -6
Hope this helps!
Answer:
My step-by-step explanation:
1. First thing we do is: Distribute
(x+8)(x−5)x
(x−5)+8(x−5)
2. Second thing:Distribute
x(x−5)+8(x−5)
x^2−5x+8(x−5)
3.Third thing: Distribute
x^2−5x+8(x−5)
x^2−5x+8x−40
4. Fourth thing: Combine like terms
x^2−5x+8x−40
x^2+3x−40
5.And finnaly we find: The solution
x^2+3x−40
Good Luck!
Its the reflections over the Y and X axis. Then count how diagonal the line is
