About LinkBacksHello, how do I solve the following problem?
Do you know how to findOriginally Posted by Artifact
If you do know how to do that, the just do it then find the length of the result.
If you do not, please explain why not. Because you are being asked to do somethings that you don't understand.
so I guess 2a is 2* 29 and 3b is 3*58? Or am I off track?
You did not answer any of those questions!Do you know how to find

WHAT IS
ok, I guess I don't know how to find 2a-3b, I thought I had to find the length of a first and then find the length of b. After that I would multiply a with 2 and b with 3. So 2a-3b would be = 58 - 174. But I guess that is the wrong way of doing it.
Hi there (=. Before we start let us understand how scalar multiplication and subtraction of vectors works.
Scalar multiplication:
Subtraction of two vectors
can be geometrically defined as follows: to subtract b from a, place the end points of a and b at the same point, and then draw an arrow from the tip of b to the tip of a. That arrow represents the vector a − b, as illustrated below:
The difference of a and b is
now find the resulting vector and find it's magnitude which you seem to know how to do.
