Answer: The pink fingernail are defined by the expression x-2 where x is the total number of fingers in both hand. For general case the number of nails with pink nail paint is 8.
Explanation:
Let the total number of fingers in both hands be x.
Since she paints 2 nails by red nail paint, therefore the number of remaining nails is x-2.
She paints pink nail paint on remaining nails, so the total number of pink nails is defined by the expression x-2.
In general case the total number of fingers in both hands is 10, therefore the number of nails with pink nail paint is 
.

Step-by-step explanation:
Answer:
Step-by-step explanation:
given that U, V are two vectors in R^n
These two vectors can be written as a linear combination of 3 vectors
w1, w2, and w3
To prove that U+V also can be written as a linear combination of these three vectors.
Since U is a linear combination we can write for not all a,b, c equal to 0
Similarly for d,e,f not all equal to 0
Adding these we have
Here all a+d, b+e or c+f cannot be simultaneously 0.
So we get U+V can be written as a linear combination of w1, w2 w3 as follows:
Proved
