Intersecting chord rule:
DK x KB = AK x CK
12 x 4x+1 = 14 x 3+3x
Simplify:
48x +12 = 42x +42
Subtract 12 from each side:
48x = 42x + 30
Subtract 42x from each side:
6x = 30
Divide both sides by 6:
x = 5
Now find the length of KB: 4x +1 = 4(5) +1 = 20 +1 = 21
Now add KB and AK:
21 + 14 = 35
The answer is D. 35
Answer:
20-3=17
5-2=3
17/3 is... 5 and 2/3
Step-by-step explanation:
Based on the given sequence of numbers above, the best definition of it would be a geometric sequence. It is a geometric sequence because term of the sequence of numbers after the first is found by multiplying the previous one by a fixed, non-zero number, and the sequence shows a common ratio.
