The answer is 5 because first you change 14 1/2 into a improper fraction then subtract the numbers.
(x - 3)(x + 3)²
(x - 3)(x + 3)(x + 3)
(x(x + 3) - 3(x + 3))(x + 3)
(x(x) + x(3) - 3(x) - 3(3))(x + 3)
(x² + 3x - 3x - 9)(x + 3)
(x² - 9)(x + 3)
x²(x + 3) - 9(x + 3)
x²(x) + x²(3) - 9(x) - 9(3)
x³ + 3x² - 9x - 27
The answer is 2.

Answer:
<em>He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins</em>
Step-by-step explanation:
<u>System of Equations</u>
Let's call
x = pounds of trail mix 5% raisins
y = pounds of trail mix 20% raisins
The distributor wants to make 1,000 pounds of trail mix, thus:
x + y = 1,000 [1]
The mix must be 8% raisings as a combination of x and y, thus:
5x + 20y = 8*1,000 = 8,000
Dividing by 5:
x + 4y = 1,600 [2]
Subtracting [2] and [1]:
4y - y = 1,600 - 1,000
Operating:
3y = 600
y = 200
From [1]
x = 1,000 - y = 1,000 - 200
x = 800
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
