What is the value of the product (4 - 21)(6 + 2/)?<br> 20 - 41<br> 20 + 161<br> 28 + 161<br> 28 - 41
xeze [42]

Answer:

  28 -4i

Step-by-step explanation:

Perhaps you want the product ...

  (4 -2i)(6 +2i)

Multiplying in the usual way, we get ...

  (4)(6) +(4)(+2i) +(-2i)(6) +(-2i)(2i)

  = 24 +8i -12i -4i^2

Recognizing that i^2 = -1, we can collect terms to get ...

  = 24 +i(8 -12) -4(-1)

  = 28 -4i

_____

Please note that i = √(-1) is not the same as 1 or /. You may need to edit your question to ensure the correct symbol is used.

A car uses 8 gallons of gasoline to travel 290 miles. How much gasoline will the car use to travel 400 miles
VARVARA [1.3K]
To find this answer, you would need to find how many miles 1 gallon of gas will take them. To find this, you would do 290÷8=36.25. So with this information, you will be able to find out how much gas it would take to travel 400 miles. You would do 400÷36.25=11.03. 11.03 would be how many gallons of gas is used to travel 400 miles. Hope this helps! ;)

Answer:

(6x - 1) • (2x + 9)

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

 ((22•3x2) +  52x) -  9

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  12x2+52x-9  

The first term is,  12x2  its coefficient is  12 .

The middle term is,  +52x  its coefficient is  52 .

The last term, "the constant", is  -9  

Step-1 : Multiply the coefficient of the first term by the constant   12 • -9 = -108  

Step-2 : Find two factors of  -108  whose sum equals the coefficient of the middle term, which is   52 .

     -108    +    1    =    -107  

     -54    +    2    =    -52  

     -36    +    3    =    -33  

     -27    +    4    =    -23  

     -18    +    6    =    -12  

     -12    +    9    =    -3  

     -9    +    12    =    3  

     -6    +    18    =    12  

     -4    +    27    =    23  

     -3    +    36    =    33  

     -2    +    54    =    52    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -2  and  54  

                    12x2 - 2x + 54x - 9

Step-4 : Add up the first 2 terms, pulling out like factors :

                   2x • (6x-1)

             Add up the last 2 terms, pulling out common factors :

                   9 • (6x-1)

Step-5 : Add up the four terms of step 4 :

                   (2x+9)  •  (6x-1)

            Which is the desired factorization

HOPE IT HELPS! :))

Ann and Betty together have $60. Ann has $9 more than twice Betty's amount. How much money does each have?
Ymorist [56]
First and mainly keep that 9 one side,
There are 2 people involved Ann and Betty, Then divide the TOTAL AMOUNT BY THE NUMBER OF PEOPLE.
· Then it will look like $60÷2= $30 per person.
In this case everyone has equal amount of money, but the question say Ann has $9 more than Betty's. so, Ann≈ $30 +$9= $39.
                                                       Betty≈ $30-$9= $21
         Because loses money because Ann has more,                        
                                      TOTAL=Ann+Betty
                                       $60= $39+$21
