30 miles
step-by-step explanation:
we know that 60 seconds equals 1 minute and 60 minutes 1 hour
44 ft 60 sec 60 min 158400 ft
* * =
1 sec 1 min 1 hour hour
we know that there are 5280 ft per mile
158400 ft 1 mile 30 miles
* =
1 hour 5280 ft 1 hour
so in 1 hour it can travel 30 miles
hello from mrbilldoesmath!
answer:
(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)
discussion:
the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,
a^3 + b^3 = (a + b) (a^2 - a b + b^2).
in our case
343x^3+216y^3 = (7x)^3 + (6y)^3
so take a = 7x and b = 6y in the above equation to get the answer.

b if for most of the graph
d if y intercept
