Answer:
Ben 3 times older than Daniel
Step-by-step explanation:
Multiply 3 times 4
The name of the polygon is an Octdecagon, or in other words, a 18-sided polygon. You find the total angles of a polygon by the formula (n - 2) * 180. What I did in this case to find the number of sides, was that I divided 2,880 by 180. My quotient was 16. Then, I added 2 in order to get 18. I did the reverse by doing (18 - 2) * 180 to check my answer, and it equaled 2,880.
Answer: The smallest possible number is 136.
Step-by-step explanation:
1. You need to find the Least common multiple (LCM), which is the smallest of the common multiples of 17 and 8.
2. You can descompose 17 and 8 into primes factors. Then, you obtain:
3. Now, you must choose commons and no commons with the greatest exponent and multiply them. Therefore the result is:
you have to apply this formula (a+b)(c-d)=ac-ad+bc-bd
-6a^3*b*5a^2+6a^3b*2ab+6a^3b*b+2ab^2*5a^2-2ab^2*2ab-2ab^2*b=
-30a^5*b+12a^4b^2+6a^3b^2+10a^3b^2-4a^2b^3-2ab^3
