Thuy planned for a square table to have a side length of 30 in, but found that it could be a little bigger at 39 in. She found the
change of scale below.
39 in. - 3 13
30 in 3 10
The changer scaleis 13 to 10
What is Thuy's error?
30 in
Thuy should have written the ratio as 3in.
30 in
Thuy should have written the ratio as 39 in-
Thuy should have divided both numbers by 6.
Thuy should have divided both numbers by 13.

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
