Select the correct answer. If A and B are dependent events, which of these conditions must be true?
OA. PIA and B) = P(A) + P(B)
OB. P(A and B)
P(A)
P(B)
OCP(BLA) = P(B)
=
OD. P(AB) = P(A)
O E. P(BA)=P(B) )

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

4+4+2x

or

2x+8
