3420°
explanation:
the equation of the sum of interior angles are (n-2)x180
polygon above has 21 sides so you sub n as 21 and plug the equation in the calculator
D= {-1}
R= {4,9,15,0}
Function? No, the relation is not a function.
Answer:
b=4.5
Step-by-step explanation:
4b+4=22
4b=22-4
4b=18
b=4.5
The equation is Oy = 3/6x
4m + 7 = -3m + 49
4m + 3m = 49 - 7
7m = 42
m = 42/7
m = 6
So, your final answer is 6
Hope this helps!
