The way that you would do this is by taking

out of the binomial, or as I like to think about it, 'un-distributing'. :p

out of

, you end up with

.
When you take

out of

, you get

.
Put it together, and the solution is

-

Hope I helped!!
Try this solution (analytic method):
1. if new line is parallel to the given one (y=3x+2) it means the new line has a form y=3x+b, where b - number.
2. In order to calculate 'b', it need to substitute the coordinates of point (6;1) into the equation of the new line:
1=3*6+b, ⇒ b=-17.
3. If to make up the equation of the new line:
y=3x-17
Answer: A
32 2/5 ÷ 2 7/10
let's turn above into improper fractions:
32 2/5 ----> 162/5
2 7/10 -----> 27/10
so,
162/5 ÷ 27/10 -------> 162/5 * 10/27 = 12 necklaces
