Atriangle 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?

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

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
