what is the perimeter?

x = -2.6875 is your answer.

Step-by-step explanation:

What you do is you need to get x by itself.

4x - 3/ 12 +11

4x -1/4 + 11 =

4x = -10 3/4

x = -2.6875 is your answer.

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

maybe showing the graph would
