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 a′b′c′d′. match each vertex of polygon a′b′c′d′ to its coordinates.

The coordinates of image are A'(1,1), B'(2,-1), C'(3,0) and D'(2,1).

Step-by-step explanation:

It is given that the vertices of polygon ABCD are at A(1, 1), B(2, 3), C(3, 2), and D(2, 1).

If a figure is reflected across the x-axis, then according to the rule of reflection

After that the figure it translated 2 units up to form polygon A′B′C′D′. According to the rule of translation

The coordinates of image are

Therefore the coordinates of image are A'(1,1), B'(2,-1), C'(3,0) and D'(2,1).

answer: it is 8

step-by-step explanation:

you know why its 8
