Answer:
A and B
A and C
Step-by-step explanation:
Common internal tangents intersect the segment joining the centers of the two circles.
Tangent I is common internal tangent to circles A and B as the line joining the centers of circles will intersect the tangent I.
Tangent I is also a common internal tangent to circle A and C.The line joining the centers of circles A and C intersects tangent I .
Tangent I is not a common internal tangent to circles B and C,
Remember these two combinations: logab=loga+logb, log(a/b)=loga-logb
3logx=logx^3
(1/2)log(x+2)=log(x+2)^(1/2)
2log(z-4)=log(z-4)^2
so the given expression can be combined into log{[(x^3)(z-4)^2]/(x+2)^(1/2)}
Answer:
52 units
Step-by-step explanation:
Perimeter = sum of it sides =
15 + 8 + 6 + 17 + 6
= 52
