Answer:

f(-3) = 21

Step-by-step explanation:

To solve this, you can replace all x's with -3 and then solve to find the answer.

f(x) = x^2 - 4x

f(-3) = -3^2 - 4(-3)

f(-3) = 9 - (-12)

f(-3) = 21

I hope this helps!

The density of glass is 2.6 g/cm3 and the density of lead is 11.3 g/cm3. Does this mean there are more particles of lead in 1 cm

Colt1911 [192]

The answer is that there are more particles in 1 cubic cm. this is because within 1 cubic cm lead has 11.3g in compared to the 2.6 glass has. m/v= density. divide the masses over the volume and that will prove your answer.
