Answer:
(x, y) = (12, 6)
Step-by-step explanation:
The problem is solved much more easily by considering groups of 2 small and 1 large boxes. Such a group will have a volume of 2·10+20 = 40 ft³, so 240/40 = 6 such groups are needed.
The number of small boxes shipped is 6·2 = 12; the number of large boxes shipped is 6.
_____
To solve this graphically, we must write two equations in x and y:
x = 2y . . . . . the number of small boxes is twice the number of large boxes
10x +20y = 240 . . . . the total volume is 240 ft³
The attached graph shows the solution of these equations.
(x, y) = (12, 6)
Answer:
0+7i
Step-by-step explanation:

The real part of the expression ('a') is zero. We have shown that, so it will be in the required form. Ordinarily, 0 would not be shown when writing this number.
__
We have taken the question to mean the principal square root. -7i is also a root of -49.
The correct answer for this question would be option B. <span>$20,408.16. So how sure are we that this is the answer. Given that Archibald wants to have $22,000 in 13 months and this has a simple interest of 7.2% a year. So we get 7.2% of 22,000 and that would be $1584 in a year for 12 months. 7.2% divided by 12 and that would be 0.6% monthly. 0.6% of 22,000 is 132. Add 1584 and 132, the result is 1, 716. Deduct 1,716 from 22,000 and the result is 20,284. The nearest answer for this would be option B. Hope this answer helps.</span>
