A^2 +a-6. You use the method of foiling where you multiply the first two terms, the the outside terms, the inside terms, then the last terms. You would do a•a, then a•-2 the a•3 then 3•-2. You would get a^2 -2a +3a -6. Then combine like terms to get your answer.

Answer:
The coordinates of Q and S are;
(-5,8) and (1,-3)
Step-by-step explanation:
When we reflect a point with coordinates (x,y) across the y-axis, we get a new point with the coordinates (-x,y)
So (5,8) becomes (-5,8)
and (-1,-3) becomes (1,-3)
These two angles are congruent so
12x + 3 = 11x + 9
X = 6
Plug in 6 so 12(6)+3=75
Both angles measure 75 degrees
