Write the perimeter of a rectangle in simplified form. The length is 7x + 1 and the width is x - 3

16x - 4

Step-by-step explanation:

A rectangle have two identical length and two identical width, so to get the perimeter

Two identical length + two identical width = perimeter

2(7x+1) + 2(x-3)

( remember to multiply everything inside the bracket with the 2)

= 14x +2 +2x - 6

= 16x - 4

90% rotation

step-by-step explanation:

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:
