We move all terms to the left:

9(2x+15)-(45)=0

We multiply parentheses

18x+135-45=0

We add all the numbers together, and all the variables

18x+90=0

We move all terms containing x to the left, all other terms to the right

18x=-90

x=-90/18

x=-5

The figure shows that the polygon:

  • Has 6 sides.
  • Divided into 4 triangles.
  • Total interior angle measure of 180°.
  • Total measure of the interior angles of this polygon is 720°.

<h3>What is the polygon about?</h3>

The polygon has sides of: AB, BC, CD, DE, EF, FA.

So, this means that they have 6 sides and when you look at the diagram, this 6 sides can be divided into 4 triangle of which whose total interior will sum up to 180°.

Since there are 4 triangles and the interior is 180°, then to get  the total measure of the interior angles of this polygon will be:

= 180 X 4 = 720

Therefore, one can say that the The figure shows that the polygon, has 6 sides, may be divided into 4 triangles, each of which will have a total interior angle measure of  180. Therefore, the total measure of the interior angles of this polygon is 720.

How can knowing the GCF and LCM help you when you add, subtract, and multiply fractions?
Stells [14]
<span>When you add fractions, the denominators must be the same, so you may have to generate equivalent fractions by using the lowest common multiple of all the denominators. For subtraction of fractions, you use the same method. When multiplying fractions, you can only multiply the numerators together, and the denominators together. </span>
