el triangulo que forma el radio es un triangulo equilátero y por lo tanto el lado del hexágono sera de la misma medida que el radio:
lado = radio = 2 cm
como hay 6 lados, lo multiplicamos por 6 :
2x6 = 12 cm
entonces el perímetro del hexágono es 12 cm

Begin by removing the brackets.
6+3(n-4)-8+2n
6 + 3n - 12 - 8 + 2n Collect like terms
3n + 2n + 6 - 12 - 8 Combine
5n - 14
Answer
5n - 14

Answer:
x = -2
y = 6
Step-by-step explanation:
i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out
12x + 15y = 66
+ <u>35x - 15y = -160</u>
47x = -94
x = -94/47
x = -2
substitute -2 for 'x' to solve for 'y':
4(-2) + 5y = 22
-8 + 5y = 22
5y = 30
y = 6
You have to foil out the problem
