Which equations illustrate the associative property of addition? choose exactly two answers that are correct.
a. (11 + 2.2) + (–5) = 11 + [2.2 + (–5)]
b. –3 • (5 + 8.5) = –3 • 5 + (–3) • 8.5
c. + 1.8 = 1.8 +
d. –7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
