The first one I THINK is 21 and the second one I THINK is 20. I'm not sure though sorry if I'm wrong
Step-by-step explanation:
f(g(-2))
= f[(-2)² + 2]
= f(6)
= -0.5(6)² + 5(6)
= 12.
<span>Complementary angles sum up to 90 degrees and supplementary angles sum up to 180 (I remember that because they are alphabetical).
90 - 71.4 = 18.6
180 - 71.4 = 108.6
Therefore, D. is the answer.</span>
Midpoint x: -6
midpoint y: 0
hope I’m right, so sorry if I’m not!
