Which of the following equations is true? A. 1.8(42.4 - 19.8) = (1.8 × 42.4) + (1.8 × 19.8) B. 1.8(42.4 - 19.8) = (1.8 × 42.4) - (1.8 × 19.8) C. 1.8(42.4 - 19.8) = 44.2 - 21.6 D. 1.8(42.4 - 19.8) = 1.8 - 1.8 × 19.8

The image of abc is a'b'c. what transformations would result in this image? abc is reflected over the line x = 1, then is rotated -90° around the origin. abc is reflected over the line y = x - 1, then t: (x, y) → (x - 1, y - 1). abc is rotated 90° around the origin, then is reflected over the y-axis. abc is rotated -90° around the origin, then is reflected over the line y = -1.
