Answer:
Length = 120 ft
Total cost = 1500$
Step-by-step explanation:
First, to find the length of the backyard we reverse the formula (A = l * w) and divide 10,800 by 90.
10,800 ft^2 / 90 ft = 120 ft.
we can check this by plugging the length of 120 ft into the formula:
120 ft * 90 ft = 10,800 ft^2.
Next, to find the cost of the single length of fence we multiply our length (120 ft) by the cost ($12.50):
120 * 12.50 = $1500
It's a half of an equilateral triangle because their angles measure 30° and 60° (an equilateral triangle has 3 angles of 60°)
So x=(2h/√3)/2=h√3=27√3≈15.6
You change the equation into a y=mx+b form so it would be y=x-6 and so when you graph it, go down six on the y-axis and make a straight line that goes diagonally through the boxes. Not sure if you were asking how to change the equation to graphing form or how to actually graph the line but hopefully this helps. :)
Answer:
25
Step-by-step explanation:
j=14
c=2j-3
2(14)-3=28-3=25
