X=13 because if it were 14 then the total amount of people would be 360. There can be 13 seats in each row is what it means.
Answer:
1)
Perimeter=24 inches
Area= around 43.46 inches
Step-by-step explanation:
1) Perimeter = 3in * number of sides
Perimeter = 3*8 = 24
Area= 2(1+ square root of 2) length of one side squared
=42.46
2)
Perimeter = 24
Area= 43.46 inches squared- 3inches
3)
Perimeter = 24
Area= 43.46- triangle area
triangle area = height x base /2
Height = 3, we can compare it.
Base = 3
Triangle = 9/2
Area = 43.46- 4.5
Area =38.96
Can't see 4 and 5 for some reason
6)
Perimeter = 30
Area = 61.94
Sorry if its incorrect, I am just 4th grade :(

4-6x=-8
-6x=-4-8
-6x=-12
x=-12/-6
x=2
When you multiply a nonzero rational and an irrational number, the outcome is irrational. It's a pretty advanced proof, having to do with a contradiction theorem. For example, 2*e is irrational.
