A triangle has a perimeter of 66 feet, if the three sides if the triangle are n, 3n+3,and 4n-9,what is the length of three sides?

Respuesta :

JwArii

Perimeter of triangle = addition of all side

65 = n+3n+5+3n+4

65 =7n+9   ------------ combined like term

56 = 7n   ---------------subtract 9 from both sides

8 = n     --------------divide by 7 to both sides

length of each side

n= 8

3n+5=3(8)+5=24+5=29

3n+4=3(8)+4=24+4=28
