Step-by-step explanation:
First you need to make a line perpendicular to y=2/3x+5. To do that you have to know that, if we use y=ax+b, a1*a2=-1. That is if a1 and a2 are perpendicular. So we get 2/3*a2=-1. -1/ 2/3=a2. a2=-1.5. We get y=-1.5x+b. Fill in (4,0) on y=-1.5x+b abd we get 0=-1.5(4)+b. b=6
Answer is D.x=9
5x+3+6x+5+8x+1=180
now solve for 'x'

The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:
Since the length is twice the width, we have 
, and the formula for the perimeter becomes
So, we have
