D iswholly part of B. so B intersect D is D
The answer is 10 because 9x5=45 then you do 45-15=30 then you divide by 3 which is 10.
Your welcome
(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 :)
