X=30 fine the whole thing first

<h3>Answer:   x = 30</h3>

=======================================================

Explanation:

If a regular polygon has n sides, then each interior angle has the measure of

i = 180(n-2)/n

In this case, we have n = 6 sides, so,

i = 180(n-2)/n

i = 180(6-2)/6

i = 120

Each interior angle of a regular hexagon is 120 degrees.

This means the bottom-right angle of the triangle is 120 degrees. The upper-right angle of that triangle is shown to be x degrees. The remaining angle is also x due to the triangle being isosceles (recall that regular hexagons have all sides the same length). Isosceles triangles have congruent base angles, which are opposite the congruent sides.

Use the fact that for any triangle, the three angles always add to 180, and we get...

x+120+x = 180

2x+120 = 180

2x = 180-120

2x = 60

x = 60/2

x = 30

Factor completely. -2k - k3^ - 3k^2
wlad13 [49]

Answer:

-k(k+1)(k+2)

Step-by-step explanation:

Begin to factor by using GCF by finding the greatest common factor. Here it is k.

-2k-k^3-3k^2 = -k(2+k^2+3k)

We will rearrange and factor the trinomial.

-k(2+k^2+3k)\\-k(k^2+3k+2)\\-k(k+1)(k+2)

As x increases by 1 what will be the rate of change for y in this equation y=-2x+6
Natali5045456 [20]

the rate of change of a linear function is the same slope

the slope of a linear function is the coefficient that accompanies the variable in this case the variable is x and the slope is -2

so, the rate of change for y is -2

Can somebody number the problem and work it out for me thanks and btw it’s solving system by graphics
adoni [48]

Answer:

Solutions are (3,1) and (4,2)

Step-by-step explanation:

Graph is shown in the attached sheet

Given are two systems of equations and we have to solve them using graph

For graphing let us first prepare table for x and y.

1) y=\frac{-2x}{3} +3:\\y=2x-5

I line                                                             II line

x     0   4.5    3                              x       0      2.5     3

y      3   0       1                              y       -5      0        1

The two lines intersect at (3,1)

Hence solution is (3,1)

--------------------------------------------

2) y=\frac{x}{2} \\-6x+3y=-18

I line                                                             II line

x     0    2    4                              x       0      6     4

y      0   1      2                             y       3      0     2

The two lines intersect at (4,2)

Hence solution is (4,2)
