Answer:

  1. P=16x+4
  2. P=17x+7

Step-by-step explanation:

  1. Solution

Perimeter of rectangle: P=l+l+w+w

Since:l=5x+2 and w=3x

P=(5x+2)+(5x+2)+(3x)+(3x)

P=5x+5x+3x+3x+2+2

P=(5+5+3+3)x+(2+2)

2. Solution

P=(4x+2)+(4x+2)+(3x)+(3x)+(3x+3)

P=(4x+4x)+2+2+(3x+3x+3x)+3

P=(4+4+3+3+3)x+(2+2+3)
