7 - (2x + 1) + 4x please show solving steps as well
1 answer:
Answer:
Step-by-step explanation:
Distribute the negative inside 2x+1
Remind that <u>negative</u><u> </u><u>multiply</u><u> </u><u>negative</u><u> </u><u>must</u><u> </u><u>equal</u><u> </u><u>positive</u><u>.</u>
variables cannot sum/add/subtract with constants.
They must be the same terms.
Therefore, our answer is 2x+6

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°.
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.
