Question

answer this question- a× ( b + c ) =​

Answer 1

Answer:

We have, d(A,C)=17;d(B,C)=6.5

Now, d(A,C)=d(A,B)+d(B,C)

So, d(A,B)=d(A,C)−d(B,C)=17−6.5

∴ d(A,B)=10.5

Answer 2

Answer:

A={a,b,c}, B={b,c,d} and C={a,d,c}

Now, A−B={a,b,c}−{b,c,d}={a}

and B∩C={b,c,d}∩{a,d,c}

={c,d}

Therefore, (A−B)×(B∩C)={a}×{c,d}

={(a,c),(a,d)}
