Answer:

5i and -5i

Step-by-step explanation:

Both of these would have to be in the equation for either of them to work, and as the problem already told us that there is only a 3rd root, neither will be our answer.

Have a great day, and feel free to comment with questions!

Answer:

5i and -5i

Step-by-step explanation:

Imaginary roots come in pairs, so the third root must be a real number.  Therefore, neither 5i nor -5i can be the third root.

Luba_88 [7]

Answer:

The correct option is;

C diseconomies of scale; coordination problems

Step-by-step explanation:

Dis-economies of scale is in effect where the average cost of production of  firm increases as it increases its inputs towards producing more. That is as the production rate increases, the unit cost of production also increases

Increase in the mean cost of production as the production rate increases is an indication of diminishing returns to increasing scale of production

Dis-economies of scale can be caused by Coordination problems

Difficulties in Co-ordination and monitoring . Where there is growth, the monitoring and coordination requirements becomes more complex, there is also the tendency for increased inefficiency and increase in average cost as the firm expands

George wants to put carpeting in a rectangular living room and a square bedroom.The length and width of the living room is 12 fe
erastova [34]

Answer:

Expression:  3.5((12x18) + 13²)

Step-by-step explanation:

Since George is going to put carpeting in two different rooms, one rectangular and one square, you need to find the area of each room, add the sum and then multiply the total area needed by the cost per square foot of carpet.  The area of a rectangle is: a = lw, where l=length and w = width.  The area of a square is: a = s², where s = side of the square.  Take the sum of these two areas would be (12 x 18) + 13² or 213 + 169 = 382.  Since the cost of the carpet is the same per square foot, you can multiply the entire sum by the cost of $3.50 or:  3.5((12 x 18) + 13²) or 3.5(382) = $1,337.
