-6r(4r - 5) - 2(r - 2)
(-6r).4r - 5.(-6r) - 2.r - 2.(-2)
-24r² + 30r - 2r + 4
-24r² + 28r + 4
Problems:
0.5x0.5 = 0.25
0.6x0.6 = 0.36
0.1x0.5 = 0.05
1.5x0.5 = 0.75
There are many problems like that. You can do 0.2, 0.3, 0.4, 0.5, etc. multiplying another integer.
Answer:
The first one is neither: 90+89=179
The second one could be either supplementary or neither: 63+47=110, but if you add the final angle measure it would be 180
The last one is complementary: 62+29=90

Look to the right of the number in the thousands
place. It's a 6, so round up.
8,636 is rounded to 9,000 because the highest place
