Seven cars and x vans can be parked in a line in 39916800 ways. find the number of ways in which five cars and x+2 vans can be parked.

Acar travels at an average speed of 56 miles per hour. how long does it take to travel 196 miles

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?

Write the equations in logarithmic form 7^3=343
