2. Consider polygon ABCD with coordinates A(8,12), B(10,4),C(4,4),D(2,8). Part A: What are the coordinates of A"B"C"D" if we reflect it over the line y = 2, then dilate
by a scale factor of-centered at the origin?

A(8,12) ► A'(?)→ A"(?)
B(10,4) →B'(?)→ B"(?)
C(4,4) → C'(?)→ C"(?)
D(2,8) ► D'(?)→ D"(?)

Find the coordinates after reflection: A′(8,−8)andB′(10,0)andC′(4,0)andD′(2,−4)

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
