Answer:
Your data is not accurate...
Answer:
10: -11n^5
12: 6k^2 -6k+7
Step-by-step explanation:
Ok so what your gonna do is add or subtract the ones with the same exponent.
so -15+4= -11 since they are both n^5 you can add them so your answer is:
-11n^2
now you have 8k^2-k-5k+7-2k. so you are gonna rearrange them so the same exponents are together.(keep the sign in front in front, if no sign it is positive)
8k^2-2k^2-5k-k+7
add like exponents
6k^2-6k+7
Answer:
285
Step-by-step explanation:
4(5x15-2)-7
4(75-2)-7
4x73-7
292-7
285
C=pi*d
=22/7*7
=22
22 is the circumference of first circle
