Based on the dimensions of the clipboard, the length of the ribbon is <u>40 inches</u><u> </u>and the area of the clipboard is<u> 99 inches ².</u>

The ribbon goes around the clipboard which means that its length is the clipboard's perimeter which is calculated as:

<em>= 2 x length + 2 x Width </em>

= 2 x 9 + 2 x 11

= 18 + 22

= 40 inches

The area of the clipboard will be:

<em>= Length x Width </em>

= 9 x 11

= 99 inches ²

In conclusion, the length is 40 inches and the area is 99 inches²

Solving Square Roots Worksheet (x - k)^2 : Part 1
iVinArrow [24]

Answer:

1. x = +/- 2\sqrt{2} - 7

2. x = 3 +/- 2i\sqrt{3}

3. n = 2 +/- i\sqrt{2}

Step-by-step explanation:

1. Divide both sides by 2: (x + 7)^2 = 8

Square root both sides: x + 7 = +/- 2\sqrt{2}

Subtract 7 from both sides: x = +/- 2\sqrt{2} - 7

2. Square root both sides: x - 3 = \sqrt{-12}

Since there is a negative inside the radical, we need to have an imaginary number: i=\sqrt{-1} . So, \sqrt{-12} =i\sqrt{12} =2i\sqrt{3}

Add 3 to both sides: x = 3 +/- 2i\sqrt{3}

3. Divide by -5 from both sides: (n - 2)^2 = -2

Square root both sides: n - 2 = \sqrt{-2}

Again, we have to use i: n-2=\sqrt{-2} =i\sqrt{2}

Add 2 to both sides: n = 2 +/- i\sqrt{2}

Hope this helps!
