Its
C. Draw a line connecting the the intersection of the arcs below and above the segment.
Answer:
width= x-7
Step-by-step explanation:
l= 8x
Area = l*b
b= 8x^2-56x/8x
b= 8x(x-7)/8x
b= x-7
Answer: 
Step-by-step explanation:
Since the center of dilation is not at the origin, we can use the following formula in order to find the coordinates of the vertices of the triangle D'E'F':

Where "O" is the center of dilation at (a,b) and "k" is the scale factor.
In this case you can identify that:

Therefore, susbtituting values into the formula shown above, you get that the coordinates ot the resulting triangle D'E'F, are the following:
Vertex D' → 
Vertex E' → 
Vertex F' →
