Question

Please please answer these questions I had exam right now

Answer 1

1.]

NO.S :- 60 & 72

LCM :- 360

FORMULA :-

                         LCM * HCF = PRODUCT OF NO.S

                    ∴  (360) * x = 60 * 72

                    ⇒ x = 12

2.]

n(A) = 4

n(B) = 6

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

n(A ∪ B) = 4 + 6                                                  || DISJOINT  HAVE ∩ = 0

n(A ∪ B) = 10

3.]

P(x) = x∧2 - 3x - 6

replacing x to -2

P(-2) = 4+12-6

P(-2) = 10

HOPE IT HELPS!!!
