Answer:
B) 11√3 - 7√6
Step-by-step explanation:
√48 can be simplified to <em>4√3</em>, and √54 can be simplified to <em>3√6</em>.
The equation is now <em>7√3 - 4√6 + 4√3 - 3√6</em>.
This can be grouped into <em>(7√3 + 4√3) + (-4√6 -3√6)</em>.
We get 11√3 - 7√6.

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
