Atriangle has a perimeter of 39 cm .if one side is increased by 2cm the other sides are increased by 1cm each in measure, what are some possible dimensions of the new triangle

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

step-by-step explanation:

ask goog great chance of finding the solution there

answer: 1+1

step-by-step explanation: 1+1 is at least 2

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
