Equilateral is the only triangle that has all the sides that are equal to each other. Hope this helped you :)
It’s the first one ( quadratic )
105% =$34.02
100% (cost without sales tax) = 34.02/1.05 =$32.40
Step-by-step explanation:
given,
x1= 1 , x2= 7 , m1= 3
y1= 4 , y2= 1 , m2= 1
x=?
y=?
using section formula
x= (m2.x1 + m1.x2)/m1 + m2
x= find yourself
y= (m2.y1 + m1.y2) / m1 + m2
y= find yourself
