If there are two parallel lines on a graph, then they are on the same plane
The third tree diagram is correct.
The probabilities for the first draw are 3/7 for green and 4/7 for red.
If you draw a green pear first, then your probabilities for the second pear would be 2/6 for green and 4/6 for red (since it is done without replacement, the number of pears to choose from changes).
If you draw a red pear first, then your probabilities for the second pear would be 3/6 for green and 3/6 for red.
Answer:
The correct answer is

Step-by-step explanation:
Method 1
We want to simplify,

The double negatives becomes positive,

We now add the whole number parts and the fractions separately

This will give us,

The least common denominator for the fractional parts is 9.




Method 2
We want to simplify,

The double negatives becomes positive,

We first convert the mixed numbers to improper fractions to obtain,

We carry out the multiplication in the numerator to get,

We add in the numerator to get,

The least common denominator is
.



We convert back to mixed numbers to get,

Answer:
-18
Step-by-step explanation:
-3xy,X=2 ,y=3
-3(2)(3)
-3(6)
=-18
2x^2+2xy+2x
The ^ means exponent
