The cost of one kilogram of cinnamon red hots is $4.00 and cost of one kilogram of gummy bears is $9.00
Step-by-step explanation:
Let,
Cost of one kilogram of cinnamon red hots = x
Cost of one kilogram of gummy bears = y
According to given statement;
3x+y=21 Eqn 1
3x+3y=39 Eqn 2
Subtracting Eqn 1 from Eqn 2
Dividing both sides by 2
Putting y=9 in Eqn 1
Dividing both sides by 3
The cost of one kilogram of cinnamon red hots is $4.00 and cost of one kilogram of gummy bears is $9.00

Since there are 3 lines (triangle), perimeter is simply the sum of those sides
find each side using distance (d) formula:
where two points of the line lie at (x1, y1) and (x2, y2)
let's name the points of our triangle to make it easier: A = (8, 2), B = (8, 6), C = (6, 6)
So now for P add AB + BC + AC = 4+2+4.47
P = 10.47 units squared
