Answer:
p(6) = 7
Step-by-step explanation:
p(n) = n + 1
Let n = 6
p(6) = 6 + 1
p(6) = 7
Answer:
7 miles
Step-by-step explanation:
35 x 0.2 = 7 miles
Lets set up the relationship of the length to width:
l = 3w
Using this, we can make all the variables the same by substitution:
2l + 2w = perimeter
2l + 2w = 72
2(3w) + 2w = 72
6w + 2w = 72
8w = 72
w = 9
The width is 9, to the length must be 9*3, or 27.
Hope this helped!
Answer:


Step-by-step explanation:
we are given
speed =8 mph
time = 6 hours
so, we have

now, we can find distance
distance = (speed)*(time)


so, we have

so, our range for x and y can be
