Triangle A''B''C'' is formed by a reflection over x=-3 and dilation by a scale factor of 3 from the origin. Which equation shows the correct relationship between ABC and A''B''C'?

Segments AB / A"B" = √13 / 2 x √13

Step-by-step explanation:

The Triangle's vertices are at points A(-3,3), B(1,-3) and C(-3,-3).

• The reflection over x = 1 shows vertices A, B and C below:

A(-3,3)→A'(5,3);

B(1,-3)→B'(1,3);

C(-3,-3)→C'(5,-3).

• The Dilation by a scale factor of 2 from the origin is expressed as:

(x,y)→(2x,2y)

Therefore,

A'(5,3)→A''(10,6);

B'(1,3)→B''(2,6);

C'(5,-3)→C''(10,-6)

The attachment below completed the calculations and shows the segment in a simple graph.
