Answer:

x⁴ - 8x² + 9

Step-by-step explanation:

The Area of the smallest square is A1 = x . x = x²

The Area of the second square is A2 = ( x² - 3 )(x² - 3)

A2 = x⁴ - 3x² - 3x² + 9

A2 = x⁴ - 6x² + 9

The Area of the Shaded shape is A2 - A1

x⁴ - 6x² + 9 - x²

x⁴ - 8x² + 9

Alenkasestr [34]

Answer:

396

Step-by-step explanation:

A = bw

A = 36w

P = 2w + 2b

94 = 2w + 2(36)

94 = 2w + 72

-72           -72

--------------------

22 = 2w

Valentin [98]
First compute the whole number of the possibilities :
10*9=90.
Compute the number of favorable possibilities:
There is 5 even numbers. Once we pick an even number, 
we pick 5. So the number of the favorable possibilities is 5.
Now we compute the probability like this:
\frac{5}{90}

<span>300 min / $12.00 = 25 minutes / dollar </span>

<span>The cost of the 300 minute card is cheaper per minute and a better value. </span>

<span>If you don't expect to use more than 200 minutes then save your money and buy the smaller card.</span>
