3n to the 2nd power+2

steposvetlana [31]

Answer:

11n

Step-by-step explanation:

We don't know the value of N, so we leave that the same.

3 to the second power, (3x3)= 9.

We have to add 2 to 9, so 9+2=11

Add your n to the end, and your answer is 11n.

jeyben [28]

Answer:

x/2=87.2

Step-by-step explanation:

Pip was thinking of a number - Let's call this number x

Pip halve the number - So half of x = x/2 (or 1/2 x)

And gets an answer of 87.2 - x/2=87.2

So your equation would be x/2=87.2

I hope this helps :)

What numbers are zeros of g(x) = x^2 - 2x - 4? take your time if you need to!

ipn [44]

Answer:

$x = 1 + \sqrt5, x = 1 - \sqrt5$

Step-by-step explanation:

Hello!

We can solve the quadratic by using the quadratic formula.

Standard form of a quadratic: $ax^2 + bx + c = 0$

Quadratic Formula: $x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}$

Given our Equation: $g(x) = x^2 - 2x - 4$

a = 1
b = -2
c = -4

Plug the values into the equation and solve.

<h3>Solve</h3>

$x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}$
$x = \frac{-(-2)\pm\sqrt{(-2)^2 - 4(1)(-4)}}{2(1)}$
$x = \frac{2\pm\sqrt{4 +16}}{2}$
$x = \frac{2\pm\sqrt{20}}{2}$
$x = \frac{2\pm\sqrt{4 * 5}}{2}$
$x = \frac{2\pm(\sqrt4 * \sqrt5)}{2}$
$x = \frac{2\pm2\sqrt5}{2}$
$x = 1 + \sqrt5, x = 1 - \sqrt5$
