6 0

To solve this polynomial equation, we first factor the left side.

To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.

These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.

So either x + 6 = 0 or x + 2 = 0 and solving for

x in each equation, our answer is {-6, -2}.

For the function h(x) =3x/(x+5)(x-4), solve the equation.​
LuckyWell [14K]

Answer:

x = 0

Step-by-step explanation:

To 'solve' means to find the x values that make the equation equal zero, so

0 = (3x)/[(x + 5)(x - 4)  

Multiply both sides by the denominator to get rid of the fraction

0[(x + 5)(x - 4)] = [(3x)(x + 5)(x - 4)]/[(x + 5)(x - 4)]

0 = 3x  

 0 = x     (divide both sides by 3)

So x = 0 is the solution for this equation

(I will mark brainlest, please help me. I'm just really confused.) (25 POINTS)
Alecsey [184]

Answer:

below

Step-by-step explanation:

for f(x) insert the x into the equation.

example:

f(-6) → -(-6+2)^2

follow pemdas

p: -(-4)^2

e: -(16) because -4 times -4 is 16.

m: -(16) → -16

Do that for the rest of the first table. As for the inverse table, f(x) and x will just switch spots. so (-6,-16) will become (-16,-6)

What are the measures of each interior and exterior angles of regular quadrilateral MNOP?
stiks02 [169]

Answer:

A regular polygon is a polygon that is equilateral and equiangular.

The only regular quadrilateral is the square.

We know that all the interior angles of a square are 90° each, so we are fine with that.

Now, for the exterior angles.

If we fix our position in the vertex, we can do from one side, to the same side, a full rotation of 360°.

Now, if we only do an external rotation, this means, from one side to other side, we will do a rotation of 360° minus the interior angle:

this is:

360° - 90° = 270°

Below is an image as a guide of this.

What is the least number of degrees you could rotate a regular pentagon (5 equal side lengths) around its center so that it appe
Leya [2.2K]

Answer:

Well, I'm not the smartest person, nor do I exactly know what you mean, but I have a wild guess that the least you could rotate it is 100 degrees.

Step-by-step explanation:

Considering the fact that it's sides are all equal, you could compare this to a square, which also has equal sides. Its angles are equal, too, so you could measure it's angles (100 degrees) and turn it that exact amount,

I hope this helps you, like I said, I don't exactly know what you are talking about, I am not studying that sort of thing yet.
