Polygon ABCDE is reflected across the x-axis to form polygon Aā€²Bā€²Cā€²Dā€²Eā€². Then polygon Aā€²Bā€²Cā€²Dā€²Eā€² is dilated by a scale factor of 0.5 about Dā€² to form polygon LMNOP. Vertices A and B correspond to L and M, respectively.

TheĀ verticesĀ ofĀ polygon ABCDĀ are at A(1, 1),Ā B(2, 3),Ā C(3, 2), andĀ D(2, 1).Ā ABCDĀ isĀ reflected acrossĀ theĀ x-axisĀ and translated 2 units up toĀ form polygonĀ - 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 :)
