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:

Answer:
I have gotten 216/61, but I am not sure if this is right.
Step-by-step explanation:
By using the "Keep It, Change It, Flip It" tactic, I was able to come up with an answer and simplify it.
1. Keep the original divisor.
162/3
2. Change the sign.
Division becomes multiplication.
3. The last fraction is reciprocated.
61/4 becomes 4/61.
IF you are solving for d:
isolate the D, do the opposite of PEMDAS.
-d/6 + 12 = -7
(subtract 12 from both sides)
-d/6 + 12 (-12) = -7 (-12)
-d/6 = -19
(multiply 6 to both sides)
-d/6(6) = -19(6)
-d = -19(6)
-d = -144
-d/-1 = -144/-1
d = 144
hope this helps
1. GCF is a factor that is shared by all terms within a polynomial for example, if we have a polynomial of the form A*B + A*C, the GCF is A since both terms have A as a factor 2. after we factor out the GCF, it is placed outside the parentheses, in front of the rest of the polynomial. using our previous example, A*B+A*C = A(B+C) 3. we can verify that our factoring is correct by distributing the GCF to the polynomial within the parentheses
