Question

7. A magnifying glass shows you an image of an object that is 7 times the object's actual size. An ant is 0.2 cm in length. What is the length of its image in the magnifying glass?
1 point
1.4 cm
14 cm
.03 cm
3 cm

8. Which isometry is equivalent to two reflections across parallel lines?
1 point
glide reflection
translation
rotation
dilation

Answer 1

The magnifying glass makes everything 7 times bigger.  So we just multiply 0.2 cm by 7 to get 1.4 cm.

Reflecting across a set of parallel lines will be the same as a translation.
