Multiply 3 to the first bracket then multiply 2 to the second bracket. 3(a+2b) + 2(3a+b) = 3a+6b+6a+2b= 9a+8b
Answer:
Answer is A
A contains all the elememts common to both the sets and thus it is the inteesection of the given two sets.

Step-by-step explanation:
we would like to expand the following logarithmic expression:
remember the multiplication logarithmic indentity given by:
so our given expression should be
by exponent logarithmic property we acquire:
hence, our answer is A
Answer:
x = - 3 with multiplicity 2
Step-by-step explanation:
f(x) = (x - 3)(x + 3)(x + 3) = (x - 3)(x + 3)²
Equating each factor to zero and solving for x
x - 3 = 0 ⇒ x = 3 with multiplicity 1
x + 3 = 0 ⇒ x = - 3
x + 3 = 0 ⇒ x = -3
Thus x = - 3 has multiplicity of 2
The fact that the factor is squared gives the multiplicity
(x + 3)³ has root - 3 of multiplicity 3
