Okay. So, what we do first is do the distributive property by multiply each number in the parenthesis by 3. When we do that, we get (6x + 12), because 3 * 2x is 6x and 4 * 3 is 12. Now, the numbers written out in long form is 5 + 6x + 12 + 6. 6x is in simplified form, because there is nothing that we can combine it with, but we do need to combine the whole numbers. 5 + 12 is 17, and 17 + 6 is 23. The expression in simplified form is 6x + 23. The answer is B.
Answer:
Option 3rd is correct that is 
Step-by-step explanation:
Since, the pennant has three points it is in triangular shape since, have three points
Triangle is enclosed figure.
As we know the sum of interior angles of triangles is 
Therefore, Option 1,2,4 are discarded.
Hence, Option 3rd is correct.
