Answer:
What's the question?
Step-by-step explanation:
(a-b) X (a+b)
= aXa - bXa +aXb -bXb (distributing)
Now, cross product of a vector with itself = 0
so, aXa = 0, bXb = 0
Also, aXb = - bXa
so,
(a-b) X (a+b) = 0 + aXb + aXb + 0
= 2aXb
hence, proved :)
Answer:
-30
Step-by-step explanation:
- Plug in the values of x and y: 6 - 3(12)
- 3(12) = 3 × 12 = 36
- Plug 36 in: 6 - 36
- 6 - 36 = -30
I hope this helps!
