This is actually pretty easy.
<span>Simplifying 4n + -9 = -9 Reorder the terms: -9 + 4n = -9 Add '9' to each side of the equation. -9 + 9 + 4n = -9 + 9 Combine like terms: -9 + 9 = 0 0 + 4n = -9 + 9 4n = -9 + 9 Combine like terms: -9 + 9 = 0 4n = 0 Solving 4n = 0 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Divide each side by '4'. n = 0 Simplifying n = 0

****hope this helps!!!! please put as brainliest if possible!!!! really appreciated!!

Answer:

The slope is 1/2

Step-by-step explanation:

To find the slope

m= (y2-y1)/(x2-x1)

= (8-2)/(5--7)

= (8-2)/(5+7)

= 6/12

= 1/2

What is the factored form of x2 – x – 2? (x – 2)(x 1) (x 2)(x 1) (x – 2)(x – 1) (x 2)(x – 1)

Alexxx [7]

A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

The factored form of the quadratic equation can be done in the following manner,

$x^2-x-2\\\\= x^2-2x+x-2\\\\=x(x-2)+(x-2)\\\\=(x+1)(x-2)$

Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

In the figure to the right, AB = 7.5 m, BC = 2.5 m, and DE = 1.25 m. Find the perimeter of the figure if all angles are right.

Citrus2011 [14]

So look at it as a normal rectangle with just four sides. AB is 7.5, which is one side. And now to get the other side just add BC and DE together to complete the side. It would be 2.5 + 1.25= 3.75. And to get the perimeter just add 3.75+3.75+7.5+7.5. I hope this makes sense.
