Since regular polygon has same sides, the perimeter of other sides are also 6cm

i found out there are 9 sides. so if question A is asking the perimeter of the whole sides except the one mentioned it will be 6cm×8 = 48cm

for question B
use \: the \: formula \: area =  \frac{a \times p}{2}
the answer is 222.55cm squared

-7  -6  -5  -4  -3  -2  -1    0    1    2    3    4    5   6    7

As you can see on the number line, both -7 and 7 are each 7 units away from 0.

You have designed an experiment manipulating room temperature (cold, warm, or hot), noise level (quiet or loud), and room color
OleMash [197]

Answer:

Option B.

2 × 3 interactions are possible.

Step-by-step explanation:

Since the experiment is manipulating room temperature, noise level, and room colour, this means that the experiment has 3 main effects, and for that reason has 3 independent variables.

Since there are 3 independent variables, there are 3! interactions.

And 3! = 3 × 2 × 1 = 2 × 3

The vertices of AABC are A(-6, -7), B(-3,-10) and
LenaWriter [7]

Answer:

A, but try the rest of the points!

Step-by-step explanation:

I assume AABC means triangle ABC

Just do the operation to each point.  so A is (-6, -7)  (x - 2. y - 7) is telling you subtract 2 from -6 and 7 from -7 or in other words it changes from  (-6, -7)  to (-6 - 2. -7 - 7) = (-8, -14)

Only one answer has that point for A', but you should really really really try the rest.

Select one of the factors of 4x^2 + 5x − 6
BARSIC [14]

Answer:

The answer to your question is: letter C

Step-by-step explanation:

                                        4x² + 5x - 6

Process

                4 x - 6 = - 24

                Find two numbers that added gives + 5 and multiply gives -24

                These numbers are + 8 and - 3

                 4x² + 8x - 3x - 6

                 4x ( x + 2) - 3(x + 2)

                (x + 2) (4x - 3)
