Answer:
d=75° e=28° f=77°
Step-by-step explanation:
The angle of a straight line is 180°

Answer:
first box: -9
second box: -20
Step-by-step explanation:
Group the terms with c and the ones without c:
9c - 15c - 3c = -9c
-12 - 8 = -20
So the simplification is -9c + -20
(which is the same as -9c - 20)
4^3 is 4*4*4=64
The exponents tell us how many times we multiply the base by itself.
