Answer:
Number of points, x, Number of segments, y
x: 2, 3, 4, 5, ... N,. ...
y: 1, 3, 6, 10, ... (N-1)(N)/2, ...
Step-by-step explanation:
Adding Nth point, there are N-1 new segments,
and (sum over {i = 1 to N-1} of i) total segments. As Gauss knew when he was c.10 yo, the sum is (N-1)(N)/2.
Answer:
32
Step-by-step explanation:
22 - 6 = 16.
16 x 2 =32
I'ts 5x, 5x and then x = 1 is 2 and then y = e equals 3 and then 2x + 3 = 5x
Answer:
45
Step-by-step explanation:
i hope this helps you :) i would do the middle one but you dont need that one
<span>1/6 (12C + 24) + 1/3(12 c - 3) =
12 c/ 6 + 4 +12c / 3 - 1 =
2c +4 + 4 c -1
6c +3 </span>
