Answer:
a(a+3) are the terms which can be cancelled.
Step-by-step explanation:
In this question if we factorize both the expressions then we can get the common factors which can be cancelled.
So first we factorize a²+3a = a( a+3 )
Now the second expression 
⇒
⇒
⇒
⇒
Now it is clear to us that factors a(a+3) are the common factors that can be cancelled.
C.
Since it is flipping vertically, it is going OVER the x-axis which is the axis that runs horizontally.
Answer:
Midpoint is ( Average of x’s, Average of y’s )
1 = (x + 7)/2
2 = x + 7, x = - 5
and - 1 = (y + (-4))/2
so - 2 = y - 4 and y = 2
Pt B = (- 5, 2)

Bolded are your answers. The others are if i missed some of the choices. To have a triangle name, it must all be angles, and no side lengths.
hope this helps
