Answer:

Here's one way to do it

Step-by-step explanation:

Divide the hexagon into triangles, for example, as in the diagram below.

The triangles are all inside the hexagon, so the sum of their interior angles is the sum of those of the hexagon.

The sum of the interior angles of a triangle is 180°.

There are four triangles, so

Sum of interior angles = 4 × 180° = 720°

20. Solve 4 - 2(b - 6) = 12<br><br>b = 2<br><br>b = 12<br><br>b = -2<br><br>b = -10

Maurinko [17]

Answer:

Option A is the correct option.

Solution,

$4 - 2(b - 6) = 12 \\ or \: 4 - 2b + 12 = 12 \\ or \: 4 + 12 - 2b = 12 \\ or \: 16 - 2b = 12 \\ or \: - 2b = 12 - 16 \\ or \: - 2b = - 4 \\ or \: b = \frac{ - 4}{ - 2} \\ b = 2$

Hope this helps...

Good luck on your assignment..

Solve the following system of equations.

timofeeve [1]

+8y and -8y cross out.

So the first one is 3x=15
Second one is 2x=10

x=5
Then plug x is one of the equations

2(5)-8y=10
10-8y=10

x=5
y=0

What is the surface area of this right rectangular prism? Enter your answer as a

mixas84 [53]

You will find all of the surface area of all of the sides and add them together to find the surface area of the retangular prisim. So, what I would do is the front and back are both 54, so 108. The sides are 27, so 54. The top and bottom are 18, so 36. Add them together, and you will get 198. I hope this helps.
