Need asap 20 two similar triangles are shown on the following coordinate grid: which set of transformations has been performed on triangle abc to form triangle a′b′c′? dilation by a scale factor of 4 followed by reflection over the x-axis dilation by a scale factor of 2 followed by reflection over the x-axis dilation by a scale factor of 4 followed by reflection over the y-axis dilation by a scale factor of 2 followed by reflection over the y-axis

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

i believe the answer is 323 ft
