As we could "drag" these together, we could then do it the easy way.
56
+56
+56
-------
168
------------------------
Or we could also do the following:
56
3:
6
3= 18.
Carry the one.
5
3 = 15+1 (which was carried). = 16
(16+8) =
168
X = 2 + √42,2- √42
decimal form: 8.480741, -4.480741
sorry if my answer isn't right
Answer:
Yes.
Step-by-step explanation:
Yes they are because that is the definition of congruency.
I don't understand what you mean but this might be the answer
Answer:
4.6%.
Step-by-step explanation:
The probability that a can of paint contains contamination(C) is 3.23%
P(C)=3.23%
The probability of a mixing(M) error is 2.4%.
P(M)=2.4%
The probability of both is 1.03%.
We want to determine the probability that a randomly selected can has contamination or a mixing error. i.e. 
In probability theory:
The probability that a randomly selected can has contamination or a mixing error is 4.6%.
