Anarel [89]
Area= length*width

width=W

W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)

Which of the following expressions is correct?
masya89 [10]

Answer:

The correct answer is: [A]: " -(-21)  =  21 " .

________________________________

Step-by-step explanation:

________________________________

Let us examine the answer choices given.

________________________________

Choice:  [A]:  " -(-21) = 21 .  This is correct;  

     → since a "negative value of negative value" is a "positive value" ; as shown in this case.  The equal sign holds true, since the

"negative of a "negative value" is equal to the "positive value" of that same "positive value equivalent."

________________________________

Choice: [B]:  " -(-21) = -21 .  This is incorrect.  As explained above:

    → a "negative of negative" is a "positive value"  .

This answer choice shows that a "negative of negative"; is a "negative" :

                                                      → which is:  INCORRECT.

    → Rule out:  "Choice:  [B]."

________________________________

Choice: [C]:  " -(21) = 21 .  This is incorrect.  The "negative" value [of a positive integer is not equal to the "equivalent positive value" of that same integer.

   → Rule out:  "Choice:  [C]."

________________________________

Choice: [D]:  " (-21) = 21 ";  This is incorrect.  In a conceptually similar way as explained above—(for  "Answer Choice:  [C]" — the "negative value equivalent" of an integer is NOT equal to the "equivalent positive value" [of that same integer.].

  → Rule out:   "Choice:  [D]."

________________________________

The correct answer is:  [A]:  " -(-21) = 21 " .

Hope this is helpful to you!
