F(x)=8x^2-2x+3
g(x)=12x^2+4x-3
what is h(x)=f(x)-g(x)?
a) h(x)=20x^2+2x
b) h(x)=-4x^2-6x
c) h(x)=-4x^2-6x+6
d) h(x)=-4x^2+2x

-4x^2-6x+6

Step-by-step explanation:

We are asked to subtract g from f.

So the problem is:

[8x^2-2x+3]-[12x^2+4x-3]

So I'm going to distribute and write without [].

8x^2-2x+3-12x^2-4x+3

Now I'm going to pair up any like terms:

8x^2-12x^2-2x-4x+3+3

Simplifying:

-4x^2-6x+6

The correct answer is- Muscular foot and unsegmented soft body.

Mollusk is the second most diversified phylum ( the first being arthropoda) of animals. Organisms under this phylum are predominantly found in the marine habitats.

The name “mollusca” corresponds to the soft body of the organism ( as the earlieast mollusk is cuttlefish, which is an unshelled organism).

Muscular foot is the locomotory organ of this phylum, which can be contracted and retracted whenever required.

Organisms belonging to this phylum share certain characteristics, including a muscular foot, a visceral mass having internal organs, and a mantle, which may or may not secrete calcareous shell ( that is made up of calcium carbonate).
