Answer:
75
Step-by-step explanation:
In running 0.6 miles, you have gone from 300 remaining to 255 remaining, so have burned ...
300 -255 = 45 . . . . . calories
The rate in calories per mile is ...
(45 cal)/(0.6 mi) = 75 cal/mi
At the rate of the first 0.6 miles, you will burn 75 calories running 1 mile.

Answer:
B: (4x - 7)(16x^2 + 28x + 49)
Step-by-step explanation:
64x^3-343 can be rewritten as 4^3x^3 - 7^3 or (4x)^3 - 7^3. This is the difference of two cubes. The appropriate formula for factoring such is
a^3 - b^3 = (a - b)(a^2 + ab + b^2). Therefore,
our (4x)^3 - 7^3 = (4x - 7)(16x^2 + 28x + 49). This is Answer B.
