4 - 7f = f - 12

Subtract f from both sides.

4 - 7f - f = -12

Subtract 4 from both sides.

-7f - f = -12 - 4

Simplify.

-8f = -16

Divide both sides by -8.

f = 2

To show your work, simply plug in the value of f into the original equation.

When f = 2, :

4 - 7f = f - 12

4 - 7(2) = (2) - 12

Simplify.

4 - 14 = 2 - 12

Simplify.

-12 = -12

So, f = 2

~Hope I helped!~

Difference of Squares gives which complex factors for the expression +3?
Oduvanchick [21]

The difference of squares is:

(x+i√3)(x-i√3)

So the correct option is the last one, D.

<h3>Which expression gives x^2 + 3?</h3>

For a complex number:

Z = a + b*i

We define the complex conjugate of Z as:

Z' = a - b*i

Such that the product between the complex number and its complex conjugate gives:

Z*Z' = a^2 + b^2

Now, of you look at option D, you can see we have the product of a number and its conjugate, then we can write the product and use the above rule to get:

(x + i\sqrt{3} )*(x - i\sqrt{3} ) = x^2 + (\sqrt{3} )^2 = x^2 + 3

Which is what we wanted to get, so that is the correct option.
