Answer:

7x^2-2x+4

Step-by-step explanation:

(5x^2+2x+11)-(7+4x-2x^2)

Breaking the parentheses using the law of signs for addition / subtraction:

5x^2+2x+11-7-4x+2x^2

Combining like terms:

(5x^2+2x^2)+(2x-4x)+(11-7)

add/subtract like terms:

7x^2-2x+4

kozerog [31]

Answer:

540 mm

Step-by-step explanation:

Here we are given a rectangular box with dimensions of the top surface as 40 mm and 230 mm

We are asked to determine the measurement of the ribbon which may go all the way around the edge of it. Basically we are being asked the perimeter of the top surface. The perimeter is given as the

P=2 (l+w)

l = 230

w = 40

P=2(230+40)

P=2 x 270

P= 540

Hence we need 540 mm of ribbon  to go all the way around the edge of the top of the box.

Is the red line a radius or diameter of the circle
insens350 [35]

The diameter of the circle would be a line going through the center of the circle connecting to both sides.

The radius of a circle would be a line only going to the the center, or in other words, half the circle.

I hope this makes sense!

This is the number of calls for the help desk

160000/3200 = 50per call

network center

735000/9800

Electronic mail

100000/10000 =

10 for the mail account

For smart phone support

124600/8900

= 14 per phone extension

<h3>b. Charges to the COMM sector </h3>

For Electronic mail

5200 * 0.25 * 0.96 * 10 per email account
