Answer:
Let be the i-th odd positive integer number,
Step-by-step explanation:
Let be the i-th odd positive integer number
It seems that the sum of the first k odd positives integers is
Note that,
thus,
Answer:
log 3(x+4) = log 3 + log (x+4)
Step-by-step explanation:
Because 3(x+4) is a product, log 3(x+4) = log 3 + log (x+4).
Answer:
2
Step-by-step explanation:
this one is correct
1/5+1/5=2/5
Answer:
20
Step-by-step explanation:
We're king of shown that it's a parallelogram, so we should assume LM = KN (we can't solve it if we don't know if it's a parallelogram).
LM = KN
3x - 4 = x + 12
2x = 16
x = 8
LM = x + 12 = 8 + 12 = 20
KN = 3x - 4 = 3*8 - 4 = 24 - 4 = 20
