B.
Let's simply look at each conjecture and determine if it's true or false.
A. 2n– 1 is odd if n is positive: Since n is an integer, 2n will
always be even. And an even number minus 1 is always odd. Doesn't matter
if n is positive or not. So this conjecture is true.
B. 2n– 1 is always even: Once again, 2n will always be even. So 2n-1 will always be odd. This conjecture is false.
C. 2n– 1 is odd if n is even: 2n is always even, so 2n-1 will always
be odd, regardless of what n is. So this conjecture is true.
D. 2n– 1 is always odd: 2n will always be even. So 2n-1 will always be odd. Once again, this conjecture is true.
Of the 4 conjectures above, only conjecture B is false. So the answer is B.
Answer: 7.33980582 x 10^0
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.

b. Line segment KM
c. Given
d. Definition of segment bisector
e. Reflexive property of congruence
f. SAS
g. CPCTC (Corresponding parts of congruent triangles are congruent)
Answer:
A = 74295.
Step-by-step explanation:
74*9*
- the last number must be a 0 or a 5.
So we try 74090/45 - not an integer
74095/45 = No
74190/45 No
74195/45 No
74295 / 45 = 1651 So that's it,
