Arectangle has an area of 100 ft2. if the rectangle is 5 ft wide, how long is it?   a. 15 ft b. 20 ft c. 45 ft d. 95 ft

20 ft because since the area is a product of two sides if you have one side you can divide the area by the side given to find the missing side.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

3.how is solving radical equations different than solving linear equations?
