Polygon ABCDE is reflected across the x-axis to form polygon A′B′C′D′E′. Then polygon A′B′C′D′E′ is dilated by a scale factor of 0.5 about D′ to form polygon LMNOP. Vertices A and B correspond to L and M, respectively.

Hope this helps
The vertices of polygon ABCD are at A(1, 1), B(2, 3), C(3, 2), and D(2, 1). ABCD is reflected across the x-axis and translated 2 units up to form polygon - 914438.

Answer:

Hi, the answer is the length of LM is 1.1.

Step-by-step explanation:

AB is reflected (which is a rigid transformation that doesn't change shape or size or length) and becomes A'B' which is also 2.20 units.

Then A'B'C'D'E' is dilated and becomes LMNOP, which changes the size and lengths. Now A'B' corresponds to LM, so the original length of 2.20 units is dilated by 0.5.

2.20 x 0.5 = 1.1

So LM = 1.1 units

Hope this helped :)
