The speed (s) an object falls varies directly with time. If the speed is 49.0m/s after 5 seconds, then what is the speed for 3 seconds?

simple 80 pieces in 1 sercing so 80*47=3760+20=3780

we are given expression: and .

in order to find it's greatest common factor, let us break it into smaller parts.

let us find greatest common factor of 54 and 27 first.

54 = 27 × 2

27 = 27 × 1

now, let us find the greatest common factor of m and m^3.

now, let us find the greatest common factor of n^4 and n^2.

therefore, following expressions are part of the greatest common factor of 54mn^4 and 27m^3n^2.

10 x 12 = 120 the tens to conte like 10,20,30,40 so i did that 12 times
