Answer: Choice A) Distributive property
We're multiplying the outer -3 with the inner x to get -3x
Also, multiply the outer -3 with the inner +4 to get -12
So that's why -3(x+4) = -3x-12
Answer:
Step-by-step explanation:

For this case we have that by definition, a direct variation is given in the form:

Where:
k: It is the constant of proportionality
According to the statement we have to:

Substituting:


On the other hand we have:


Answer:

Answer: B
Step-by-step explanation:

Actually Welcome to the Concept of the volumes.
Here given as, r= 6.2 mm, h = 10.8 mm, π=3.14
hence, the volume of the cone is
Volume = 1/3(πr^2h)
===> vol = 1/3(3.14*(6.2)^2*(10.8))
==> Vol = 1/3*(1303.57)
==> Vol = 434.52 mm^3
Hence the volume of the cone is 434.52 mm^3
