Answer:
Square
Step-by-step explanation:
Plot the vertices of the quadrilateral PQRS on the coordinate plane (see attached diagram). The diagram shows that this is a square. Let's prove it.
1. Find all sides lengths:

All sides have the same lengths.
2. Find the slopes of all lines:

Since the slopes of PQ and RS are the same, lines PQ and RS are parallel. Since the slopes of QR and SP are the same, lines QR and SP are parallel.
The slopes
and
have the product of

then lines are pairwise perpendicular.
This means PQRS is a square.
Answer:
180 minutes
Step-by-step explanation:
Starting with the distance formula ...
d = rt
dividing by the coefficient of t will give an equation for t:
t = d/r
Ryan's rate of 4 miles per hour can be expressed in minutes as 4 miles per 60 minutes. The Ryan's time is ...
t = (12 mi)/(4 mi/60 min) = 12·60/4 min = 180 min
Ryan's time is 180 minutes.
The stem is the left side and the leaf is the right side of the vertical line.
The leaf would be 6.
The answer is B.
