Tell whether each equation has no solution, one solution, or infinitely
many solutions.
a. 1 + 3x = 3x + 1
b. 4x + 1 = 3x + 2
C. 5x + 1 = 5x – 2
d. -3(x + 1) = -3x + 3

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

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
