45L + 30D = 360 ...reduce by dividing by 15 = 3L + 2D = 24
65L + 35D = 470...reduce by dividing by 5 = 13L + 7D = 94
3L + 2D = 24......multiply by 7
13L + 7D = 94...multiply by -2
------------------
21L + 14D = 168 (result of multiplying by 7)
-26L - 14D = - 188 (result of multiplying by -2)
-----------------add
-5L = - 20
L = -20/-5
L = 4
3L + 2D = 24
3(4) + 2D = 24
12 + 2D = 24
2D = 24 - 12
2D = 12
D = 12/2
D = 6
so the loaves of bread (L) cost $ 4 per loaf and the buns (D) cost $ 6 per dozen
It would be: 4√6 + 5√6 = 9√6
In short, Your Answer would be 9√6
Hope this helps!

Step-by-step explanation:
The number after 3 is below 5 so you would round down to 0.563.
Hi there!
![\large\boxed{(x -3)(x + 2)(x + 1)}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%28x%20-3%29%28x%20%2B%202%29%28x%20%2B%201%29%7D)
We can use long division to find the other roots of p(x).
We know that x + 1 is a factor, so:
Set up:
Find how many times that the first term in the divisor goes into the first of the dividend. Subtract from like terms.
x² - x - 6
x + 1 | x³ + 0x² - 7x - 6
x³ + x²
0 - x² - 7x
- x² - x
0 - 6x - 6
-6x - 6
0 0
Therefore, x² - x - 6 is another factor. We can factor this further:
Find two numbers that add up to -1 and multiply into -6. We get:
-3, 2
(x - 3)(x + 2)
The entire polynomial factored is:
(x -3)(x + 2)(x + 1)
