im a boy so i looked it up on google here is what i found.
Use a wide-toothed comb, wash your hair in sections, dont wash your hair every day he tighter your curls, the less frequently your hair may need to be washed. If you do need to wash your hair more frequently, you can use a dry shampoo in between those washes.
Don’t “wash, rinse, and repeat”--that style advice may work for people with straighter hair, but it’s no good for those with curly hair. When you wash your hair, only wash it once, but make sure that it’s a thorough wash so that all dirt and oil is removed from your hair.
If needed, you can wash your hair with conditioner (called “co-washing”) in-between washes. That way you won't be harming your hair with sulfates, which are found in most shampoos.[1] Keep in mind that co-washing is great for retaining moisture but only mildly cleanses the hair.

Answer:
Hello,
Step-by-step explanation:
The well-known magic square. (first apparition in China).
Here it the methode du Marquis de Liouville: (odd square:3,5,7,9,11,13,...)
We are going to put successively the number from 1 to n² (here n=3)
We imagine that the square is put on a sphere;
We begin in the middle of the last line where we put 1
ICI:
We move in direction SE of one case and put le next number
until we reach of multiple of n
After have reached a multiple of n, we move verticaly of one case
and we go to ICI until we reach n²
I don't think this is possible.
The factors of -9 are:
-1 x 9
-9 x 1
-3 x 3
And when you add them together you get:
-1 + 9 = 8
-9 + 1 = -8
-3 + 3 = 0
Sorry but there is not an answer. :(
The value of a is between 0 and 1.
