Whats the mass if the weight is 3N

What is the mass of 3 kg?

So, to answer your question, weight=mass*gravity, so 3kg*9.8m/s^2=29.4 kgm/s^2. Kilogram meters per second squared is the unit for force also known as Newtons (N). So, your book has a weight of 30 N. Weight is a function of mass (M) and gravity (g).

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
