Question

Polygon ABCD is dilated by a scale factor of 2 with the center of dilation at the origin to create polygon A′B′C′D′. If the endpoints of AB¯¯¯¯¯ are located at (0, -7) and (8, 8), what is the length of A'B'¯¯¯¯¯¯¯? Use the distance formula to help you decide:


d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√

Answer 1

As a start : find the length of AB by using the distance formula

Answer 2

ok

Answer 3

17

Answer 4

?

Answer 5

yes! since you're dilating the picture by a factor of 2,
the length also increases by a factor of 2

Answer 6

multiply the length of AB by 2 to get the length of A'B'

Answer 7

68 would me answer

Answer 8

whats the value of 17*2 ?

Answer 9

34

Answer 10

so 34 would be the length of A'B'

Answer 11

ok THank you XD

Answer 12
