Which expressions are equivalent to 7x - 14? check all that apply. a.14 - 7x b. x - 2 - 7x) d.7(x - 2) e.3x - 14 + 4x f.2x - 10 + 5x + 4

c d and e are correct

Step-by-step explanation:

not b dont lisen to the other person

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

- 70

this is the answer for you hope it
