You must know that : (a-b) ^2 = a^2 - 2ab + b^2 so let a=x and b=2, applying above formula you'll get f(x) = x^2 - 4x +4 + 4 =x^2 - 4x +8 Hope you got it ;-) Revert back if you still face any trouble.
Answer:
There are <u>2.22 grams</u> of clay are in each pot.
Step-by-step explanation:
Given:
Dakota has 4/10 kg of clay. He divides the clay to make 888 equal-sized pots.
Now, to find the number of grams of clay are in each pot.
Dakota has clay = ![\frac{4}{10} \ kg.](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B10%7D%20%5C%20kg.)
So, by using conversion factor we convert it into grams:
![\frac{4}{10} \times 1000\\\\=\frac{4000}{10} \\\\=400\ grams.](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B10%7D%20%5Ctimes%201000%5C%5C%5C%5C%3D%5Cfrac%7B4000%7D%7B10%7D%20%5C%5C%5C%5C%3D400%5C%20grams.)
Quantity of clay he has = 400 grams.
Number of equal-sized pots to make = 888.
Now, to get the quantity of grams of clay are in each pot we divide number of equal-sized pots to make by quantity of clay he has:
![\frac{888}{400}](https://tex.z-dn.net/?f=%5Cfrac%7B888%7D%7B400%7D)
![=2.22\ grams.](https://tex.z-dn.net/?f=%3D2.22%5C%20grams.)
Therefore, there are 2.22 grams of clay are in each pot.
Answer:
