In the figure, polygon abcd is dilated by a factor of 2 to produce a’b’c’d’ with the origin as the center of dilation. point a’ is at (2, 1), (-2, -2), (1, 2) or (-2, 2) , and point d’ is at (-2, 2), (4, -2), (4, 2), or (-2, -2)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
