Answer:
C) AB = BC = CD = DA = 2√5
Step-by-step explanation:
Given
A(1, 4)
B(3, 0)
C(1, −4)
D(−1, 0)
We get the distance between point A and point B
AB = √((3-1)²+(0-4)²) = √20 = 2√5
BC = √((1-3)²+(-4-0)²) = √20 = 2√5
CD = √((-1-1)²+(0-(-4))²) = √20 = 2√5
DA = √((1-(-1))²+(4-0)²) = √20 = 2√5
C) AB = BC = CD = DA = 2√5
Answer:
B
Step-by-step explanation:
15x-12<15x (distribute the 3) so it becomes 15x-13
-12<0 (group like terms)
It Should be 15/x for what I see in my notes
