a) (2/5) x 35 = 14 students received invitations
b) 35-14 = 21 students didn’t receive invitations
All of them could be as A would be an equilateral B,C,D would be irregular triangles and 3 would be an Isosceles triangle but if you had to go with one it would be A
A is the answer because if you calculate the answer correctly. that will be so.
D^2 - 4d = 3d
d^2 - 7d = 0
d(d - 7) = 0
d = 0 or d - 7 = 0
d = 0 or d = 7
I think its a
because the line segments connect each other.
