(2c^{-5})^{3} simplify ​
andrew-mc [135]

Answer:

Step-by-step explanation:

If this is

(2c^{-5})^3 then you distribute the 3 to both terms inside the parenthesis (the 2 and the c^-5).  2 cubed is 8.  The rule for the power to power is that you multiply the powers together to get -15.  So the final simplification is

8^{-15}

Two automobiles start together from the same place and travel along the same route. The first averages 40 miles
natita [175]

Answer:

A. (55 x 5) - (40 x 5)

Step-by-step explanation:

You are solving how much miles (further along) would the second car be after 5 hours.

The first car averages 40 miles per hour. 5 hours later, it will have averaged about 200 miles in 5 hours (40 x 5 = 200).

The second car averages 55 miles per hour. 5 hours later, it will have averaged about 275 miles in 5 hours (55 x 5 = 275)

Subtract: 275 - 200 = 75

The second car would have averaged 75 more miles than the first car.
