svlad2 [7]

Answer:

  9 ft, 28 ft, 26 ft

Step-by-step explanation:

The perimeter is the sum of side lengths, so ...

  P = a + b + c

  63 = n +(4n -8) +(2n +8) . . . . fill in the given side lengths

  63 = 7n . . . . . . simplify

  9 = n . . . . . . . . divide by 7

  4n -8 = 36 -8 = 28 . . . . second side length

  2n +8 = 18 +8 = 26 . . . . third side length

The side lengths are 9 ft, 28 ft, 26 ft..
