Answer:
Step-by-step explanation:
5c^5-c+c^5+7c-2
add like terms
=6c^5-c+7c-2
subtract like terms
=6c^5+6c-2
=2(3c^5+3c-1)

Step-by-step explanation:
b = age of Bailey
c = age of Celine
b + c = x
c = b + 8
so, using that identity in the first equation
b + b + 8 = x
2b + 8 = x
or, to go "after" c (Celine) :
b = c - 8
c - 8 + c = x
2c - 8 = x
2c = x + 8
c = (x + 8)/2
in x years c will have increased to c+x, and b to b+x.
so,
b + x + c + x = x + 2x = 3x
and
2c - 8 = 3x
2c = 3x + 8
c = (3x + 8)/2
Answer: B) 4536
Step-by-step explanation:
Given : A company plans to assign identification numbers to its employees. Each number is to consist of four different digits from 0 to 9, inclusive, except that the first digit cannot be 0.
i.e. The number of choices for first digit = 9 (Total digits = 1)
The number of choices for second digit = 9 (one get fixed in first place and 0 can be used)
Similarly, The number of choices for third digit = 8 ( two got fixed on 1st and second place)
The number of choices for fourth digit = 7 (Three places are fixed.)
By Fundamental counting principle ,
The number of different identification numbers are possible =
The number of different identification numbers are possible is 4536.
Therefore , the correct answer is (B) 4,536.
