Answer:

D. 3x² - x - 6

Step-by-step explanation:

If f(x) = 3x² - 4 and g(x)= x+2, find .

We know that (f - g)(x) = f(x) - g(x)

Then

(f - g)(x) = (3x² - 4) - (x+2)

= 3x² - 4 - x - 2

= 3x² - x - 4 - 2

= 3x² - x - 6

Law of cosines.Anyone good in Trigonometry?

marin [14]

Answer:

$c=11.8\ units$

Step-by-step explanation:

we know that

The formula of law of cosines is equal to

$c^2=a^2+b^2-2(a)(b)cos(C)$

where

a, b and c are sides. C is the angle opposite side c

In this problem we have

$a=3\ units\\b=10\ units$

$C=120^o$

substitute the given values

$c^2=3^2+10^2-2(3)(10)cos(120^o)$

$c^2=109-(60)cos(120^o)$

$c^2=109-(60)(-0.5))$

$c^2=109+30$

$c^2=139$

$c=11.8\ units$
