Answer:</h2>
<h2>
Step-by-step explanation:</h2>
In this problem we have two vectors:
So we need to find two things:
and:
FIRST:
In this case we have the multiplication of vectors by scalars. A scalar is a simple number, so:
SECOND:
If we name:
Then, is the magnitude of the vector 
. Therefore:
A. 0.15 Because its making me type twenty characters.
Answer:
Bottom right graph is the correct answer
First factor out 2
2(x^4 - y^4)
Rewrite it as ((x^2)^2) and ((y^2)^2)
Then you get..
2 ((x^2)^2) - (y^2)^2))
Now both terms are perfect squares, factor using the difference of squares formula, a^2 + b^2 = (a+b)(a-b)
a= x^2 and b= y^2
2((x^2 + y^2)(x+y)(x-y))
clean it up!
2(x^2 + y^2)(x+y)(x-y)
Answer:it’s 3y3 (x2 +4) (x +2 (x-2) hope this helps.
