Answer:
(x+1)(x+3)
Step-by-step explanation:
Let's factor x^2+4x+3
x^2+4x+3
The middle number is 4 and the last number is 3.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 4
Multiply together to get 3
Can you think of the two numbers?
Try 1 and 3:
1+3 = 4
1*3 = 3
Fill in the blanks in
(x+_)(x+_)
with 1 and 3 to get...
(x+1)(x+3)
It would be worth approximately $84. This is calculated by setting up a function to determine the depreciation value after a 5 year period
Let's see
![\sf [0.5\:0.5]\left[\begin{array}{cc}\sf b_1 &\sf r_1\\ \sf b_2&\sf r_2\end{array}\right]](https://tex.z-dn.net/?f=%5Csf%20%5B0.5%5C%3A0.5%5D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D%5Csf%20b_1%20%26%5Csf%20r_1%5C%5C%20%5Csf%20b_2%26%5Csf%20r_2%5Cend%7Barray%7D%5Cright%5D)
r_1 and r2 are costs per pound
So
- It's r_1 is the cost of 1/2 pound rice at market one and r_2 is at market 2
