Answer:

D

Step-by-step explanation:

7x² - 56x = 63 ( divide through by 7 )

x² - 8x = 9

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = 9 + 16

(x - 4)² = 25 ( take square root of both sides )

x - 4 = ± \sqrt{25} = ± 5 ( add 4 to both sides )

x = 4 ± 5

Then

x = 4 - 5 = - 1

x = 4 + 5 = 9

solutions are (- 1, 9 ) → D

David express company was asked to deliver 325 boxes of apples. according the rule, the delivery fee is
Andrew [12]

Answer:

22 boxes were lost.  Look for the happy squirrels.

Step-by-step explanation:

Let x be the number of lost boxes.  David Express should expect to receive  $25 for each of the 325 boxes of apples.  That means:

($25)*(325) = $8125

The loss of a box means that the delivery fee would be forfeited, which would amount to:  x*($25)

But a compensation fee of $75/box also applies, so the total loss to the income would be x*($25+$75) or x*($100).  This would be subtracted from the total expected income of $8125:

Resulting Income:   $8125 - ($100)x = $5925

$8125 - ($100)x = $5925

$8125 - ($100)x = $5925

-100x = -2200

x = 22 boxes were lost.                    Zounds! [A metric term for %$%^&]

===================

<u>Check:</u>  Does the loss of 22 of the 325 boxes result in a total payment of $5925?

Delivered boxes:  (325 - 22) = 303 boxes delivered.  303*$25 = $7575

Penalty of $75 per lost box:  22*($75) = $1650

Result:  $7575 - $1650 = $5925  <u>YES</u>
