Dwayne walks a total of 960 feet around 3 sides of a square city block. Which
2 answers:
Answer:
The perimeter is 1280ft
Step-by-step explanation:
Let the side length of the square be s.
Then the distance around three sides is 3s.
According to the question the distance around 3 sides of a square city block is 960 feet.
This implies that:
The perimeter of a square is
Substitute s=320 to get:
The perimeter is 1280 ft

The slopes of two parallel lines must be identical.
We have slope
, so the slope for the parallel line be the same.
Now, to find an equation that also passes through the given point, we use slope-point form,
, where our point 
is substituted for 
.
Now, we convert to slope-intercept form as such.
And we are done. :) We can verify graphically that these are indeed parallel lines. See attached.
