In the expression ax+bx, a is a decimal and b is a fraction. how do you decide whether to write a as a fraction or b as a decimal?

f(x) = x^2 - x - 12

Step-by-step explanation:

The function is f(x) = (x + 3)(x - 4), or f(x) = x^2 - x - 12.  Here, a = 1, b = -1, and c = -12.

HOPE THIS HELPED ;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
