12x+12
12(10)+12
12×10= 120
120+12= 132
Y = mx + c
m = 2
y = 2x + c
At (5, 0)
0 = 2(5) + c
c = -10
y = 2x - 10
(420 + 144) / 6 =
564/6 =
$ 94.....each person paid $ 94
This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.
