A quadrilateral has vertices at (1, 4),
(7, 3), (3, −5), and (8, −4). The
quadrilateral is dilated by a scale factor of
3.5 with the origin as its center. What are
the coordinates of the vertices of the
image of the quadrilateral?

answer: i don't understand it

step-by-step explanation: sorry

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
