Answer:
16x + 4
Explanation:
perimeter of rectangle: 2(Length + Width)
Here the length is 3x - 1 and the width is 5x + 3
using the formula:
2(3x - 1 + 5x + 3)
2(8x + 2)
Step-by-step explanation:
length of rectangle = 5x + 3
width of rectangle = 3x - 1
Perimeter of rectangle = 2 x width + 2 x length
⇒ perimeter = 2(3x - 1) + 2(5x + 3)
⇒ perimeter = 6x - 2 + 10x + 6
⇒ perimeter = 16x + 4
