Step-by-step explanation:
given the perimeter is
64ft
the length l= 3w
we know that the perimeter of a rectangle is given as
P=2l+2W
but L=3w
64=2(3w)+2w
64=6w+2w
64=8w
divide both sides by 8 we have
w=64/8
w=8ft
also
let the lenght of the rectangle be l
side of hexagon=l-4
perimeter of hexagon
P=5(l-4)
P=5l-20
width of rectangle w=l-2
perimeter of rectangle= 2l+2w
but w=l-2
5l-20= 2l+2(l-2)
5l-20=2l+2l-4
5l-20=4l-4
5l-4l=-4+20
l=16ft
perimeter of hexagon
P=5(l-4)
put l=16
perimeter of hexagon
P=5(16-4)
p=5(12)
P=60ft

I don't have the grid, so you'll have to actually plot the points and draw the line yourself. But I can help you calculate some points to plot.
Let's start off with 0 gallons of shampoo. So 0 times $40 = $0 and we have a fixed cost of $400. So the result is $0 + $400 = $400. And there's your first point (0, 400).
Now let's do 1 gallon of shampoo. 1 times $40 = $40 and we have to add the fixed cost of $400, so the result is $40 + $400 = $440. And your second point is (1,440).
In fact, we can create the function
c(x) = 40*x + 400
to express the cost for any amount of shampoo. So let's calculate 3 more points
c(2) = 40*x + 400 = 40 * 2 + 400 = 80 + 400 = 480
c(3) = 40*x + 400 = 40 * 3 + 400 = 120 + 400 = 520
c(4) = 40*x + 400 = 40 * 4 + 400 = 160 + 400 = 560
So 3 more points to plot are (2,480), (3,520), and (4,560).
And you've gotten your 5 points. They are (0,400), (1, 440), (2, 480), (3, 520), and (4, 560). Just plot them on your chart and draw a straight line through all 5 of them. And they will be in a straight line, if they're not, then you plotted them incorrectly.
