Answer:
p=0
Step-by-step explanation:
subtract 10p from both sides that leaves 8+p=12-4 12-8=4 p=4-4 p=0
9514 1404 393
Answer:
2160°
Step-by-step explanation:
The sum of interior angles of a convex n-gon is ...
angle sum = 180(n -2)°
When n=14, the angle sum is ...
angle sum = 180(14 -2)° = 2160°
Answer:
The number is 11
Step-by-step explanation:
6x+38=9x+5
3x=33
x= 11
N is the amount of sides
sum=13 times 180 =2340
This can be factored into (x+9)(x+5)/(x+9)(x+1)
once simplified, it's (x+5)/(x+1)
The denominator cannot be negative, so x≠-1
Therefore, the answer is C.
