You will have two find the square root of the question
Answer:
b = -18
Step-by-step explanation:
(3 + 4i) (-3-2i)
When we foil:
-9 + -6i + -12i + -8i^2
-8i^2 = +8
Combine like terms:
-1 + -18i
The correct answer is: [D]: "distributive" .

Note the "distributive property of mutliplication" :
_________________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab <span>− ac ;

Experimental is the actual measured desiredoutcome/totaltrials
total trials=10+12+28=50
green is 28
so 28/50 or 14/25 is the experimental proablity of doing green
theoretical is desired/total possible,
total possible=total number of marbles=5+8+12=25
desired=8, so 8/25 is theoretical probablity of draing green
I would expect the experimental proabblity to approach the value of the theoretical proabblity, not sure why tho
