Answer:
B. 
Step-by-step explanation:
The given quadratic trinomial is;

Comparing this to
, we have a=5,b=17,c=6.

Two factors of 30 that add up to 17 is 15 and 2.
We split the middle term to obtain;

We factor by grouping;

Factor further

The correct answer is B.
Answer:A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
Step-by-step explanation:
Answer:
10(2y+2)= 10.2y+10.2
20y+20-y
2(8y-8)=2.8y-2.8
20y+20-y=16y-16
20y-16y-y=-20-16
3y=-36
36/3y=?
y=-12
