The correct numbers to use in solving problems about
spans of time like B.C. and A.D. should be “integers”.
Integers are whole numbers (not a fractional number or not a decimal
number) which can take a value of negative, zero, or positive number. Example
of integers would be -1, 0 and 1.
<span>In calculations, the time period would be on the x-axis. Since
B.C. and A.D. are two different spans of time, therefore in the calculations,
the date of BC should be negative (negative x-axis) while the date of AD should
be positive (positive x-axis). This would place the origin as the common
reference.</span>
Answer:
The 2nd answer would be the correct option.
Step-by-step explanation:
Hope this helps:) Also can I have brainliest if possible:) It is ok if you can not.
Answer:
10
Step-by-step explanation:
5 - 5 = 0 You would want to subtract five from zero giving you -5.
Answer:
18
Step-by-step explanation:
David=x
Michelle=x-2
Karen=x-2+6=x+4
sum of ages=62
x+x-2+x+4=62
3x=60
x=20
age of Michelle=20-2=18
Answer:
x-3
Step-by-step explanation:
(x
2
−9)=(x−3)(x+3)
(x
3
−27)=(x
3
−3
3
)=(x−3)(x
2
−3x+9)
(x
2
−8x+15)=(x−3)(x−5)
∴ H.C.F. of (x
2
−9),(x
3
−27) and (x
2
−8x+15) is x−3.
