4 - 4x³ + 20x² - 20x

Step-by-step explanation:

(g × f)(x) = g(x) × f(x) = (x³ + 5x)(4x - 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x³(4x - 4) + 5x(4x - 4) ← distribute both parenthesis

= 4 - 4x³ + 20x² - 20x

This can also be done using FOIL, that is

(x³ + 5x)(4x - 4)

= 4 - 4x³ + 20x² - 20x

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
