The answer is a.0
Concentric means these circles would have the same center, thus, the smaller circle must be inside the bigger circle. Any tangent line to the smaller circle wont be a tangent line to the bigger circle, since that tangent line would intersect at the bigger circle at 2 points. Any tangent line to the big circle will not touch the small circle... so the answer would be 0.
5x =61-6
5x= 55
X = 55/5
X = 11
The explicit formula is D. -4n + 15.
Answer:
27
Step-by-step explanation:
135 divided by 5 (divide both sides by 5)
12 + n
if you substitute n for any whole number and simplify. you will find that 12+n does not equal any others. for example, i used 6 in place of n and all equations gives you 10 except 12+n
hope this helps!
