The perimeter of the rectangle is 14x + 4, the length of the rectangle is 2x. What is the width of the rectangle?

5x+2

Step-by-step explanation:

P=2L+2W

14x+4=2(2x)+2W

14x+4=4x+2W

14x+4-4x=2W

14x-4x+4=2W

10x+4=2W

(10x+4)/2=W

5x+2=W

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
