Answer:
x = 2
AB = 14
Step-by-step explanation:
2x(10) = 8(x+3)
20x = 8x + 24
subtract 8x from both sides
12x = 24
x = 2
Check:
4(10) = 8(5)
40 = 40
Correct
2x = 2 x 2 = 4
4 + 10 = 14

Answer:
(c) 4 left, CCW 90°
Step-by-step explanation:
Any of the image segments is perpendicular to the corresponding pre-image segment, so rotation is 90°. There is no reflection or rotation of 180° involved (eliminates choices A and D.
Points A and D that started in the 2nd quadrant are in the 3rd quadrant after the transformation. This tells you the rotation is CCW, not CW. (eliminates choice B) Even before you figure what translation is involved, the only reasonable choice is C: translation left 4 and rotation 90° CCW.
