8/1 + (x-1)/(x+4)
You need the same common denominator (bottom number) to be able to add together so multiply 8 by (x+4) to both bottom and top
8 (x+4)/(x+4) + (x-1)/(x+4)
Add
8 (x+4)+(x-1)/ (x+4)
Distribute the 8 to (x+4)
8x+32+x-1 / x+4
Simplify
9x+31/x+4

The triangles are similar because of one triangle is 2x bigger than the other there seems to be a dilation. And since on triangle is 2x bigger the dilation between both triangles would be 2. I hope this helped :)
Answer:
A) y = 4
Step-by-step explanation:
Line AB is a vertical line, so a line perpendicular to it would have to be a horizontal line (perpendicular lines make an "x" shape with one another). Horizontal lines are written as y = ___ .
The perpendicular line also has to pass through the point (2,4). Points are written as (x, y). Therefore, the y-value in (2,4) is 4.
The perpendicular line has to be y=4 since it passes through both the Line AB and the given point.
