4(x + 2) = 4x + 2
Are these two Equivalent

no they're not

Step-by-step explanation:

4(x+2) = 4x +8

4x+2= 4x+2

No they are not equivalent

First we would have to solve 4(x+2)

In order to solve this we need to multiply. So 4×X is equal to 4x. 4×2=8 Therefore when solving Its 4x+8..and 4x+8 is not equivalent to 4x+2

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

ur right ive taken the test
