I think it is 7060.54 it was all mental sorry
Hi!
To answer this, first we have to find how much 1 notebook costs. We can do this by dividing:
Cost/amount = ?
Or in this case
5.25/5 = 1.5
Now we have to find how much 3 notebooks cost. We can do this by multiplying:
Cost of one x amount = ?
Or in this case
1.5 x 3 = 3.15
The answer is 3.15
Hope this helps! :)
The degree of a polynomial is the highest power of the polynomial.
The polynomial is ![\mathbf{P(x) = (x + 3)^4}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28x%29%20%3D%20%28x%20%2B%203%29%5E4%7D)
The degree is given as:
![\mathbf{n = 4}](https://tex.z-dn.net/?f=%5Cmathbf%7Bn%20%3D%204%7D)
The zero is given as:
![\mathbf{x = -3}](https://tex.z-dn.net/?f=%5Cmathbf%7Bx%20%3D%20-3%7D)
Add 3 to both sides
![\mathbf{x + 3= 0}](https://tex.z-dn.net/?f=%5Cmathbf%7Bx%20%20%2B%203%3D%200%7D)
From the question, we understand that the polynomial has a single zero.
So, the polynomial is:
![\mathbf{P(x) = (x + 3)^n}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28x%29%20%3D%20%28x%20%2B%203%29%5En%7D)
Substitute 4 for n
![\mathbf{P(x) = (x + 3)^4}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28x%29%20%3D%20%28x%20%2B%203%29%5E4%7D)
Hence, the polynomial is ![\mathbf{P(x) = (x + 3)^4}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28x%29%20%3D%20%28x%20%2B%203%29%5E4%7D)
