Answer:
b) 
Step-by-step explanation:
We can use the discriminant 
to determine how many real solutions a quadratic equation in the form 
has.
- discriminant > 0 ⇒ 2 real solutions
- discriminant = 0 ⇒ 1 real solution
- discriminant < 0 ⇒ no real solutions
Exact form 81/4 Decimal form 20.25 Mixed number form 20 1/4
Writing an equation would be most helpful, but depending on the situation drawing a diagram or reading a table could work better.
The arithmetic sequence formula should help you
An= A1+ (n-1)d or An= a + d(n−1)
An= the term that you want to find.
A1 = first term in the list of ordered numbers
n = the term position (ex: for 5th term, n = 5 )
d = common difference of any pair of consecutive or adjacent numbers
So, looking the 4 choices you have the only one that follow the sequence of the formula is C
I believe the one you choose is Fibonacci sequence.
There different number of sequences:
1- arithmetic sequence
2- geometry sequence
3- Fibonacci sequence
Each of that sequences have their own formula.
So, the answer it might be C
Hope that help you
The formula for the Arithmetic is:
An = A1 + F x ( n- 1)
I believe answer is C
Because the one you chose is
I divided 56 by 4 to see how much per CD Brad payed. This got me $14. $42 divided by $14 is $3, so he can buy 3 CDs.
