Find the perimeter of a rectangle when it’s length is three times it’s width and the area is 108

Step-by-step explanation:

Let w = width

Then 3w = length

A= LW

108 = (3w)(w)

108 = 3w2

36 = w2

6 = w   18 = length  Perimeter = 2(6) + 2(18) = 48 in

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
