Answer:
12 weeks
Step-by-step explanation:
If John is aiming to save $100, with $6 a week and he has already saved $28. The leftover amount to be saved is $100 - $28 = $72
In one week → $6
2 weeks → $12
3 weeks → $18
and so on..
![\frac{72}{6} = 12](https://tex.z-dn.net/?f=%5Cfrac%7B72%7D%7B6%7D%20%3D%2012)
John will need 12 more weeks to save a total of $100.
Remember that the terms of a polynomial are the parts of the polynomial separating by addition and subtraction; in other words, the parts separated by (+) and (-) signs. Knowing this, we can separate the terms of our polynomial:
![a^2-ab+8b+b^2-1](https://tex.z-dn.net/?f=a%5E2-ab%2B8b%2Bb%5E2-1)
- First term:
![a^2](https://tex.z-dn.net/?f=a%5E2)
- Second term:
![-ab](https://tex.z-dn.net/?f=-ab)
- Third term:
![8b](https://tex.z-dn.net/?f=8b)
- Fourth term:
![b^2](https://tex.z-dn.net/?f=b%5E2)
- Fifth term:
![-1](https://tex.z-dn.net/?f=-1)
We can conclude that there are
5 terms in the polynomial
![a^2-ab+8b+b^2-1](https://tex.z-dn.net/?f=a%5E2-ab%2B8b%2Bb%5E2-1)
