Answer:

3x+12

Step-by-step explanation:

Follow the PEMDAS/GEMDAS order. First, distribute the 2 to the numbers in the parenthesis:

2(x+6)-4+x

↓

2x+16-4+x

Then, subtract the numbers without a variable (the numbers without x):

2x+16-4+x

↓

2x+12+x

Then, add the variables together (the numbers with x):

2x+12+x

↓

3x+12

Hope this is the answer you need.

For the function below, state the x-coordinate of the x-intercept that is located to the fight of the origin.

OLga [1]

Answer:

x = 3

Step-by-step explanation:

It should NOT be "fight of the origin", rather "right of the origin".

Now let's move on to solve the question...

The x-intercept is found by setting the function equal to 0. Thus:

0 = x^3 - 9x

Let's solve this using algebra:

$0=x^3-9x\\0=x(x^2-9)\\0=x(x-3)(x+3)$

Hence, x = -3 and x = 3

The coordinate that is to the right of the origin is the positive one, so x = 3 is the x-intercept we are looking for.

What is the measure of a single interior angle of a regular 34-gon?

netineya [11]

Answer:

The measure of a single interior angle is 169.4°

Step-by-step explanation:

Angles in Regular Polygons

The sum of the interior angles, in degrees, of a regular polygon, is given by the formula 180(n – 2), where n is the number of sides.

For a regular 34-gon, n=34, and the sum of the interior angles is:

180(34 – 2)=5,760°

The measure of any of the interior angles is

$\frac{5,760}{34}=169.4^\circ$

The measure of a single interior angle is 169.4°
