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

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
