If f(x)=3/4X+5/6WHAT IS F(12)-------------

Andreyy89

F(X) means the function of X. So we just plug in 12 for X.
(3/4(12))+5/6=36/4+5/6=9+5/6=59/6

What is the additive inverse of the complex number 9-412<br> -9-41<br> -9 +41<br> 9 - 41<br> 9 + 41

Studentka2010 [4]

Additive inverse means the sum should be 0

so all you gotta do is multiply the complex number by -1

(the question isn't clear so I can't state the option)

Which are the solutions of x2 = –7x – 8?

Yanka [14]

You can start by rewriting the equation so that the right side equals zero. Add $-7x$ and $8$ to both sides.

$x^2+7x+8=0$

You can now use the quadratic equation (below), where $a=1, b=7,$ and $c=8$ , to find solutions. Plug in these values for $a, b,$ and $c$ into the equation and simplify.

$\frac{-b \pm \sqrt{b^2-4(ac)}} {2a}$
$\frac{-7 \pm \sqrt{7^2-4(1 \times 8)}} {2 \times 1}$
$\frac{-7 \pm \sqrt{49-32}} {2}$
$\frac{-7 \pm \sqrt{17}} {2}$

The final answer is the combination of both solutions.
$x=\frac{-7}{2} \pm \frac{\sqrt{17}} {2} \approx -3.5 \pm 2.06.$

Or approximately...
$x=(-3.5-2.06) \approx -5.56, (-3.5+2.06) \approx-1.44$

Simplify (a+b)^3 + (a-b)^3 + 6a(a^2-b^2)

11111nata11111 [884]

Answer:

8a^3.

Step-by-step explanation:

(a+b)^3=a^3+b^3+3a^2b+3ab^2

(a-b)^3=a^3-b^3-3a^2b+3ab^2

(a+b)^3+(a-b)^3=2a^3+6ab^2

According to the question

(a+b)^3+(a-b)^3+6a(a^2-b^2)

Put in the value

=2a^3+6ab^2 +6a^3–6ab^2

=8a^3
